UC3770 - High Performance Stepper Motor Drive Circuit

Datasheet Summary

Description

The UC3770A and UC3770B are high-performance full bridge drivers that offer higher current and lower saturation voltage than the UC3717 and the UC3770.

Included in these devices are LS-TTL compatible logic inputs, current sense, monostable, thermal shutdown, and a power H-bridge output stage.

Features

  • Full-Step, Half-Step and Micro-Step Capability. Bipolar Output Current up to 2A. Wide Range of Motor Supply Voltage: 10.
  • 50V Low Saturation Voltage Wide Range of Current Control: 5mA.
  • 2A. Current Levels Selected in Steps or Varied Continuously. Thermal Protection and Soft Intervention.
