Product Summary

The UC3770AN is a kind of high-performance full bridge driver that offers higher current and lower saturation voltage than the UC3717 and the UC3770. Included in the UC3770AN are LS-TTL compatible logic inputs, current sense, monostable, thermal shutdown, and a power H-bridge output stage. Two UC3770AN and a few external components form a complete microprocessor-controllable stepper motor power system.
