AH5773 document number: ds 35444 rev. 2 - 2 1 of 17 www.diodes.com january 2015 ? diodes incorporated new product AH5773 single phase motor driver with internal hall effect latch sensor description the AH5773 is a high performance , single chip solution for driving single - coil brushless direct current (bldc) fans and motors. the integrated full - bridge driver output stage uses soft switching to minimize audible switching noise and electromagnetic interference (emi) providing a low noise solution . to simplify circuit design and minimize external components, the device integrates a stable high sensitivity hall - e ffect sensor, voltage and temperature compensated internal references, amplifiers and the output h - br idge power switches with low r dson . for system flexibility, the m otor speed can be controlled by changing the duty ratio of the pwm signal at the pwm pin or adjusting the supply voltage. to help protect the motor coil, the AH5773 provides rotor lock prote ction which shuts down the output drive if rotor lock is detected. the device automatically re - starts when the rotor lock is removed. in case of over - voltage, the device shuts down the output drive and enters standby mode to help prevent over - v oltage stress on the coil. over - temperature shutdown provides thermal protection for the device. the device enters standby mode when pwm pin is pulled low for longer than 65ms. in standby mode, AH5773 consumes less than 100 a. a tachometer output is provided by open - drain frequency generator (fg) pin which allows external interface to monitor motor rotation or speed. the fg output is the magnetic change frequency. the AH5773 is available in space saving small low profile u - dfn2020 - 6 and mso p - 8ep package s . features ? supports s ingle - p hase f ull w ave bldc f an / m otor d rive ? wide o perating v oltage r ange : 2.4 v to 18v ? built - in h igh s ensitivity hall e ffect s ensor ? built - in h - bridge with l ow r dson r esistance ? pwm i nput for s peed c ontrol ? standby f eature with i dd <100 a ? soft s witching for l ow n oise dc f an m otor a pplications ? rotor lock protection with a utomatic r e - s tart ? t off c lear w hen pwm i s l ow for g reater t han 65ms ? over v oltage s hutdown ? thermal p rotection ? tachometer (fg) o utput ? small l ow - p rofile p ackage : u - dfn2020 - 6 and msop - 8ep with e xposed p ads for p ower h andling c apability ? totally lead - free & fully rohs compliant (notes 1 & 2) ? halogen and antimony free. green device (note 3) pin assignments (top view) msop - 8ep (top view) u - dfn2020 - 6 applications ? 5 v/ 9v/ 12v/ 15v min. bldc cooling fans and motors ? net b ook/ note b ook and desktop bl dc f ans ? instruments c ooling f ans ? medium voltage / low power bldc motor s note s: 1 . no purposely added lead. fully eu directive 2002/95/ec (rohs) & 2011/65/eu (rohs 2) compliant. 2. see http://www.diodes.com/quality/lead_free.html for more information about diodes incorporateds definitions of hal ogen - and antimony - free, "green" and lead - f ree . 3. halogen - and antimony - free "green products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total br + cl) and <1000ppm antimony compounds . 8 7 6 5 f g n c o 2 p w m n c v d d o 1 g n d 1 2 3 4 p a d p w m v d d o 2 1 2 3 6 5 4 f g o 1 g n d p a d

AH5773 document number: ds 35444 rev. 2 - 2 7 of 17 www.diodes.com january 2015 ? diodes incorporated new product AH5773 application note dc supply v oltage s peed c ontrol motor speed can be controlled by varying the v dd supply voltage while pwm pin is tied to v dd pin. for example, with 12v nominal motor, changing supply voltage between 12v to 2.4 v, spee d can be reduced from 100% to 20 % typically. pwm s peed c ontrol motor speed can also be adjusted by applying a pwm speed control signal into the pwm pin while keeping the v dd pin at nominal motor voltage. the motor speed is proportional to the pwm signal duty. for example, with 12v nominal motor, v dd pin is maintained at 12v typical while varying the pwm control signal duty to adjust the motor speed linearly. the f igure below shows the output o1 and o2 in relation to pwm speed control signal at pwm pin. frequency of pwm speed - control signal can be betwe en 50 hz to 50khz. recommended typical pwm signal frequency is 25khz to keep switching frequency away from audible band. AH5773 has a very good input to output pwm linearity ov er the operating range for no load conditions (i . e . no motor coils connected to the output). when the motor coil is connected, the nonlinearity of coils and permanent magnet pro file will introduce non - linearity to the motor speed against input pwm duty rat io. if pwm signal level at pwm pin stays low for longer than 65ms typical, the outputs are disabled. depending on the motor design and its inertia, at nominal voltage (i.e. 12v for 12v motor), minimum start - up pwm duty requ ired can be typically between 20% - 45 % while minimum runnin g pwm duty can be down to 10% - 25 % typical. if voltage at v dd is lower than the nominal motor voltage, both start - up pwm duty and minimum running pwm duty required will be higher. 0 10 20 30 40 50 60 70 80 90 100 0 10 20 30 40 50 60 70 80 90 100 output pwm duty ratio (%) input pwm duty ratio (%) input to output pwm linearity (no load) vdd = 2.4v vdd = 3.0v vdd = 5.0v vdd = 12v vdd = 18v t a = +25 c p w m o 1 o 2 f g s n m a g n e t i c f l u x d e n s i t y ( b ) 0 10 20 30 40 50 60 70 80 90 100 0 10 20 30 40 50 60 70 80 90 100 output pwm duty ratio (%) input pwm duty ratio (%) input to output pwm linearity (no load) ta= - 40 ta= +25 ta= +105 v dd = 12v
