TMI8870B - 3.6-A Brushed DC Motor Driver

This page provides the datasheet information for the TMI8870B, a member of the TMI8870 3.6-A Brushed DC Motor Driver family.

Datasheet Summary

Description

The TMI8870/B device are the brushed-DC motor drivers for printers, appliances, industrial equipment, and other small machines.

Two logic inputs control the H-bridge driver, which consists of four N-channel MOSFETs that can control motors bidirectionally with up to 3.6-A peak current.

Features

  • H-Bridge Motor Driver Drives One DC Motor, One Winding of a Stepper Motor, or Other Loads.
  • Wide 6.8V to 45V Operating Voltage.
  • 3.6-A Peak Current Drive.
  • PWM Control Interface.
  • Integrated Current Regulation.
  • Low-Power Sleep Mode.
  • VM Undervoltage Lockout (UVLO).
  • Overcurrent Protection (OCP) - Retry after OCP: TMI8870 - Latch after OCP: TMI8870B.
  • Thermal Shutdown (TSD).
  • Automatic Fault Recovery.
  • ESOP8 Small Package and Footprint.
