3936  
DMOS THREE-PHASE  
PWM MOTOR DRIVER  
Designed for pulse-width modulated (PWM) current control of three-  
phase brushless dc motors, the A3936SED is capable of peak output currents  
to ± 3 A and operating voltages to 50 V. Internal fixed off-time PWM current-  
control timing circuitry can be configured to operate in slow-, fast- and mixed-  
decay modes.  
ABSOLUTE MAXIMUM RATINGS  
at T = +25°C  
A
Load Supply Voltage, VBB ........................... 50 V  
Output Current, IOUT................................... ±3 A*  
Logic Supply Voltage, VDD......................... 7.0 V  
Logic Input Voltage Range, VIN  
Internal synchronous rectification control circuitry is provided to  
improve power dissipation during PWM operation.  
(tW>30 ns).......... -0.3 V to VDD + 0.3 V  
(tW<30 ns)................ -1.0V to VDD +1V  
Sense Voltage, VSENSE................................. 0.5 V  
Reference Voltage, VREF ................................ VDD  
Package Power Dissipation,  
PD ............................................... 3.9 W  
Operating Temperature Range,  
Internal circuit protection includes thermal shutdown with  
hysteresis, and crossover current protection. Special power up sequencing is  
not required.  
The A3936 is supplied in a 44-pin plastic PLCC with a copper  
batwing tabs (suffix ‘ED’). The power tabs are at ground potential and need  
no electrical isolation. This device is also available in a lead-free version  
(100% matte tin leadframe).  
TA ................................ -20°C to +85°C  
Junction Temperature, TJ ......................... +150°C  
Storage Temperature Range,  
TS............................... -55°C to +150°C  
* Output current rating may be limited by duty cycle,  
ambient temperature, and heat sinking. Under any set of  
conditions, do not exceed the specified current rating or a  
junction temperature of 150°C.  
Features  
±3 A, 50 V Continuous Output Rating  
Low rDS(on) Outputs (typically 500 msource, 315 msink)  
Configurable Mixed, Fast and Slow Current-Decay Modes  
Synchronous Rectification for Low Power Dissipation  
Internal UVLO and Thermal Shutdown Circuitry  
Crossover-Current Protection  
Tachometer Output for External Speed Control Loop
