General 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.

Two UC3770As or UC3770Bs and a few external components form a complete microprocessor-controllable stepper motor power system.
