4/4 rev. a cautions in using the ic 1. absolute maximum ratings we are careful enough for quality control about this ic. so, ther e is no problem under normal operation, excluding that it exc eeds the absolute maximum ra tings. however, this ic might be destroyed when the absolut e maximum ratings, such as impressed voltages or the operating temperature range, is exceede d, and whether the destruction is short circuit mode or open circuit mode cannot be specified. please take into consideration the physical counter measures for safety, such as fusing, if a particular mode that exceeds the absolute maximum rating is assumed. 2. reverse polarity connection connecting the power line to th e ic in reverse polarity (from that recommended) w ill damage the part. pl ease utilize the direct ion protection device as a diode in the supply line and motor coil line. 3. power supply line due to return of regenerative current by reverse electromotive force, using electrolytic and ceramic suppress filter capacitors (0.1f) close to the ic power input terminals (vcc and gnd) iare recommended. please note the electrolytic capacitor value decreases at lower temperatures and examine to dispense physical measures for safety. 4. gnd line please keep the gnd line the lowest potential always, and check the gnd voltage when transient voltages are connected to the ic . 5. thermal design do not exceed the power dissipation (pd) of the package specific ation rating under actual operation, and please design enough t emperature margins. this product has exposed the frame to the back side of the package, but please note that it is assumed to use heat radiation ef ficiency by the heat radiation for this part. please take the heat radiation pattern on not only the surface of the substrate but also the back of t he substrate widely. 6. short circuit mode between terminals and wrong mounting do not mount the ic in the wrong direction and displacement, and be careful about the reverse-connection of the power connector . moreover, this ic might be destroyed when the dust short the terminals between them or gnd. 7. radiation strong electromagnetic radiation can cause operation failures. 8. aso (area of safety operation) do not exceed the maximum aso and the absolute maximum ratings of the output driver. 9. tsd (thermal shut-down) the tsd is activated when the junction temperature (tj) exce eds tjmax, and the output terminal is switched to open. the guarantee and protection of set are not purpose. therefore, please do not use this ic after tsd circuit operates, nor use it for assumption that operates the tsd circuit. 10. capacitor between output and gnd if a large capacitor is connected between the output and gnd, this ic might be destroyed when vcc becomes 0v or gnd, because t he electric charge accumulated in the capacitor flows to the output. please set said capacitor to smaller than 0.1f. 11. inspection by the set circuit board the stress might hang to ic by connecting the capacitor to the terminal with low impedance. then, please discharge electricity in each and all process. moreover, when attaching or detaching from jig in the inspection process, please turn off the power before mounting th e ic, and turn on after mounting the ic, and vice versa. in addition, please take into consideration the countermeasures for electrostatic damage, such as giving the earth in assembly process, transportation or preservation. 12. input terminal this ic is a monolithic ic, and has p + isolation and p substrate for the element separation. theref ore, a parasitic pn junction is firmed in this p-layer and n-layer of each element. for instance, the resistor or the trans istor is connected to the terminal as shown in the figure b elow. when the gnd voltage potential is greater than the voltage potential at terminals a on the resistor, at terminal b on the transistor, the pn junction operates as a parasitic diode. in addition, the parasitic npn transistor is formed in said parasitic diode and the n layer of surrounding elements clos e to said parasitic diode. these parasitic elements are formed in the ic because of the voltage relation. the parasitic element operating causes the inter ference of circuit operation, then the wrong operation and destruction. therefore, please be careful so as not to operate the parasitic elements by impressin g to input terminals lower voltage than gnd (p substrate). please do not apply the voltage to the input terminal when the power-supply voltage is not impr essed. moreover, please impress each input terminal lower than the power-supply voltage or equal to the specified range in the guaranteed voltag e when the power-supply voltage is impressing. simplified structure of ic 13. earth wiring pattern if small signal gnd and large current gnd exist, disperse their pattern. in addition, for voltage change by pattern wiring imp edance and large current not to change voltage of small signal gnd, each ground terminal of ic must be connected at the one point on the set circuit boa rd. as for gnd of external parts, it is similar to the above-mentioned. 14. reverse-rotation braking in the case of reverse-rotation braking from high-speed rotation, pay good attention to reverse electromotive force. furthermor e, fully check output current and consider the revolutions applied to the reverse-rotation brake. 15. about the capacitor between spvm and pgnd the capacitor between spvm and pgnd absorbs the change in a steep voltage and the current because of the pwm drive, as a result , there is a role to suppress the disorder of the spvm voltage. however, the effect falls by the influence of the wiring impedance etc, if t he capacitor becomes far from ic. please examine the capacitor between spvm and pgnd to arrange it near ic. terminal-a parasitic element gnd p + p terminal-a terminal-b gnd p p-substrate cb gnd e e c b gnd surrounding elements
