TMI8870B - 3.6-A Brushed DC Motor Driver

Download the TMI8870B datasheet PDF. This datasheet also covers the TMI8870 variant, as both devices belong to the same 3.6-a brushed dc motor driver family and are provided as variant models within a single manufacturer datasheet.

General 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.

Key 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.
