A4950 - Full-Bridge DMOS PWM Motor Driver

Datasheet Summary

Description

Designed for pulse width modulated (PWM) control of DC motors, the A4950 is capable of peak output currents to ±3.5 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.
  • A4950K is AEC-Q100 Grade 1 qualified.
  • Commercial temperature grade (A4950E:.
  • 40°C to 85°C ).
  • Au.
