UC3770B, UC3770A High Performance Stepper Motor Driver

UC3770B Description

High Performance Stepper Motor Drive Circuit UC3770A UC3770B .
The UC3770A and UC3770B are high-performance full bridge drivers that offer higher current and lower saturation voltage than the UC3717 and the UC3770.

UC3770B 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 Va

UC3770B Applications

* where high-side diodes are not required. Thresholds for the UC3770B are tailored for half stepping applications where 50%, 71%, and 100% current levels are desirable. The UC3770A and UC3770B are specified for operation from 0°C to 70°C ambient. BLOCK DIAGRAM SLUS403A - FEBRUARY 2000 UDG-92039-1
