UC3770A - High Performance Stepper Motor Driver

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.
