Designed for PWM (pulse width modulation) control of DC motors, the A4952 and A4953 are capable of withstanding peak output currents of up to ±2 amps and peak operating voltages of 40 volts.
It provides input terminals to control the speed and direction of the DC motor through an externally applied PWM control signal. An internal synchronous rectification control circuit reduces power consumption during pulse-width modulation (PWM) operation.
Internal circuit protection includes overcurrent protection, motor ground or power shorting, overheating shutdown due to hysteresis, VBB undervoltage monitoring, and crossover current protection.
The A4952 is available in an ultra-thin 10-pin MSOP package and the A4953 is available in an ultra-thin 8-pin SOICN package. Both packages have exposed pads for improved heat dissipation and are lead-free, with 100% matte tin plating on the pin frame.
