A4952 - Full-Bridge DMOS PWM Motor Drivers

Description

Designed for pulse width modulated (PWM) control of DC motors, the A4952 and A4953 are 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.

Features

  • Low RDS(on) outputs.
  • Overcurrent protection (OCP) ▫ Motor short protection ▫ Motor lead short to ground protection ▫ Motor lead short to battery protection.
  • Low Power Standby mode.
  • Adjustable PWM current limit.
  • Synchronous rectification.
  • Internal undervoltage lockout (UVLO).
  • Crossover-current protection.
  • Fault output (A4952 only).
  • Selectable retry (A4952 only).
