A3936 DMOS Three-Phase PWM Motor Driver
±3 A, 50 V continuous output rating Low rDS on outputs typically 500 mΩ source,
315 mΩ sink 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

Package 44-pin PLCC suffix ED

Designed for pulse-width-modulated PWM current control of three-phase brushless DC motors, the A3936 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.

Internal synchronous rectification control circuitry is provided to improve power dissipation during PWM operation.

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 internally fused leads three on each side for enhanced heat dissipation. These leads are at ground potential and need no electrical isolation. This device is lead Pb free version, with 100% matte tin leadframe plating.
