DRV8848 - Dual H-Bridge Motor Driver

General Description

The DRV8848 provides a dual H-bridge motor driver for home appliances and other mechatronic applications.

The device can be used to drive one or two DC motors, a bipolar stepper motor, or other loads.

A simple PWM interface allows easy interfacing with controller circuits.

Key Features

  • Dual H-Bridge Motor Driver.
  • Single/Dual Brushed DC.
  • Stepper.
  • 4 to 18V Operating Supply Voltage Range.
  • Low ON-resistance: HS + LS = 900mΩ (Typical, 25°C).
  • PWM Control Interface.
  • Optional Current Regulation With 20μs Fixed Off-Time.
  • High Output Current per H-Bridge.
  • 2A Maximum Driver Current at 12V and TA = 25°C.
  • Parallel Mode Available Capable of 4A Maximum Driver Current at 12V and TA = 25°C.
  • Low-.
