A3936 General Description
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.
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.
