Description
●Designed for pulse width modulated (PWM) control of two DC motors, the A4954 is capable of peak output currents to ±2 A and operating voltages to 40 V.
●Input terminals are provided for use in controlling the speed and direction of a DC motor with externally applied PWM control signals. Internal synchronous rectification control circuitry is provided to lower power dissipation during PWM operation.
●Internal circuit protection includes overcurrent protection, motor lead short to ground or supply, thermal shutdown with hysteresis, undervoltage monitoring of VBB, and crossover current protection.
●The A4954 is provided in a low-profile 16-pin TSSOP package with exposed thermal pad (suffix LP) that is lead (Pb) free, with 100% matte tin leadframe plating.
