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. 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 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).
