1.2 v with a maximum voltage of 19.3 v typical (internal clamp circuit). this voltage is used internal to switch the upper drivers of the u, v and w outputs. f motor fg 3n pp -------------------- = 2001 jul 11 9 philips semiconductors product speci?cation brushless motor controller (bmc12) sza1015 handbook, full pagewidth mgt196 12 v (1) (3) (4) (2) up-un wp-wn vp-vn 0 v u 12 v 0 v v 12 v 0 v w fig.8 phase condition of hall input and output voltage (motor running with e c >e cr ). (1) in this example, a pwm output signal with a 25% duty cycle is drawn as a thin line. the average motor voltage (drawn with a thicker line width) is 25% v ddm , i.e. 3.0 v. at the opposite side of the coil (in this drawing pin w) the duty cycle is 75%, so the average voltage on pin w is 9.0 v. the differential voltage over the motor pins then is: 9 - 3=6v. (2) there is still a current flowing from pin u into the motor. the lower flyback diode starts conducting, and causes a flyback voltage of around 0.7 v below gnd, until the current is zero. (3) there is still a current flowing from the motor into pin u. the upper flyback diode starts conducting, and causes a flyback voltage of around 0.7 v above v ddm , until the current is zero. (4) during this phase, the driver output is 3-state. because there is no current flowing through pin u, the back-emf of the motor is seen. 2001 jul 11 10 philips semiconductors product speci?cation brushless motor controller (bmc12) sza1015 limiting values in accordance with the absolute maximum rating system (iec 60134). thermal characteristics characteristics v dd =5v; v ddm = 12 v; gnd = 0 v; t amb =25 c; r osc =47k w , c osc = 100 pf; unless otherwise speci?ed. symbol parameter min. max. unit v dd supply voltage - 0.5 +6.5 v v ddm motor supply voltage - 0.5 +15 v i ddm motor current - 2.1 a p tot total power dissipation - 3.0 w t stg storage temperature - 55 +150 c t amb ambient temperature 0 85 c symbol parameter value unit r th(j-c) thermal resistance from junction to case 10 k/w symbol parameter conditions min. typ. max. unit supplies v dd supply voltage 4.5 5.0 5.5 v v ddm motor supply voltage 4.5 12.0 14.5 v i ddm motor current -- 2.1 a handbook, halfpage 0 50 100 150 t amb ( c) p tot (w) 4 3 1 0 2 mgt197 fig.9 maximum dissipation as a function of the ambient temperature. the ic is thermally connected with its heatsink to an external heatsink at ambient temperature, with a total thermal resistance of 35 k/w (10 k/w junction to case plus 25 k/w case to surrounding). 2001 jul 11 11 philips semiconductors product speci?cation brushless motor controller (bmc12) sza1015 notes 1. the pwm frequency is: 2. clamping level with v ddm =12v. 3. the maximum useful range of the control input voltage e c is 0 to 2 e cr (midpoint reference voltage). when e c =e cr , then no torque is applied to the motor. the conversion characteristic does not have a dead zone. i dd supply current start = high - 15 - ma i dd(q) quiescent current in power saving mode start = low -- 1ma p tot total power dissipation -- 3.0 w t amb ambient temperature 0 - 85 c hall ampli?er inputs (pins un, up, vn, vp, wn and wp) v io input offset voltage - 3.5 - +3.5 mv v i input voltage range 0 - 4.0 v v i(dif)(p-p) hall ampli?er input voltage (peak-to-peak value) 25 -- mv hall elements bias (pin bias) i bias bias current -- 32 ma v bias bias voltage i bias = 32 ma 0.1 - 0.5 v oscillator f osc oscillator frequency note 1 - 3.0 - mhz thermal shutdown circuit t sd thermal shutdown operating temperature 140 155 170 c power switches r ds(on) d-mosfet on-resistance (high or low) v ddm = 12 v 0.25 0.35 0.50 w v ddm = 5 v 0.35 0.50 0.71 w booster v capy booster output voltage note 2 19 19.3 19.6 v torque control (pins ec and ecr) v ecr reference voltage on pin ecr 1.2 1.8 2.5 v v ec torque control voltage on pin ec note 3 0 - v dd v digital input (pin start) v ih high-level input voltage 2.0 -- v v il low-level input voltage -- 0.8 v open-drain output (pin fg) v ol low-level output voltage i o =2ma -- 0.5 v symbol parameter conditions min. typ. max. unit f pwm f osc 33 --------- = 2001 jul 11 12 philips semiconductors product speci?cation brushless motor controller (bmc12) sza1015 application information handbook, full pagewidth mgt198 100 w + 5 v 22 nf 10 nf 100 pf 47 k w sza1015 332 4 3 v or 5 v + 5 v + 12 v signals to/from decoder from microcontroller 5 6 7 8 10 11 12 14 30 29 23 13, 16, 22 21 19 remf r emf (1) rlim r lim (1) fg ec ecr cp1 cp2 capy gnd v ddm v ssa 24 v dd w cosc rosc wn 2 bias wp hw 28 27 vn vp hv 26 25 un up hu hall elements + 5 v wn bias wp hw vn vp hv un up hu motor start u v 15, 17, 20 1 fig.10 typical application diagram.

soldering introduction to soldering surface mount packages this text gives a very brief insight to a complex technology. a more in-depth account of soldering ics can be found in our data handbook ic26; integrated circuit packages (document order number 9398 652 90011). there is no soldering method that is ideal for all surface mount ic packages. wave soldering is not always suitable for surface mount ics, or for printed-circuit boards with high population densities. in these situations reflow soldering is often used. re?ow soldering reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. several methods exist for reflowing; for example, infrared/convection heating in a conveyor type oven. throughput times (preheating, soldering and cooling) vary between 100 and 200 seconds depending on heating method. typical reflow peak temperatures range from 215 to 250 c. the top-surface temperature of the packages should preferable be kept below 230 c. wave soldering conventional single wave soldering is not recommended for surface mount devices (smds) or printed-circuit boards with a high component density, as solder bridging and non-wetting can present major problems. to overcome these problems the double-wave soldering method was specifically developed. if wave soldering is used the following conditions must be observed for optimal results: use a double-wave soldering method comprising a turbulent wave with high upward pressure followed by a smooth laminar wave. for packages with leads on two sides and a pitch (e): C larger than or equal to 1.27 mm, the footprint longitudinal axis is preferred to be parallel to the transport direction of the printed-circuit board; C smaller than 1.27 mm, the footprint longitudinal axis must be parallel to the transport direction of the printed-circuit board. the footprint must incorporate solder thieves at the downstream end. for packages with leads on four sides, the footprint must be placed at a 45 angle to the transport direction of the printed-circuit board. the footprint must incorporate solder thieves downstream and at the side corners. during placement and before soldering, the package must be fixed with a droplet of adhesive. the adhesive can be applied by screen printing, pin transfer or syringe dispensing. the package can be soldered after the adhesive is cured. typical dwell time is 4 seconds at 250 c. a mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. manual soldering fix the component by first soldering two diagonally-opposite end leads. use a low voltage (24 v or less) soldering iron applied to the flat part of the lead. contact time must be limited to 10 seconds at up to 300 c. when using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 c. 2001 jul 11 16 philips semiconductors product speci?cation brushless motor controller (bmc12) sza1015 suitability of surface mount ic packages for wave and re?ow soldering methods notes 1. all surface mount (smd) packages are moisture sensitive. depending upon the moisture content, the maximum temperature (with respect to time) and body size of the package, there is a risk that internal or external package cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). for details, refer to the drypack information in the data handbook ic26; integrated circuit packages; section: packing methods . 2. these packages are not suitable for wave soldering as a solder joint between the printed-circuit board and heatsink (at bottom version) can not be achieved, and as solder may stick to the heatsink (on top version). 3. if wave soldering is considered, then the package must be placed at a 45 angle to the solder wave direction. the package footprint must incorporate solder thieves downstream and at the side corners. 4. wave soldering is only suitable for lqfp, tqfp and qfp packages with a pitch (e) equal to or larger than 0.8 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. 5. wave soldering is only suitable for ssop and tssop packages with a pitch (e) equal to or larger than 0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm. package soldering method wave reflow (1)
