The UC3770ANG4 is a high-performance full bridge Stepper Motor Driver Circuit offers higher current and lower saturation voltage than the UC3717 and the UC3770. Included in this device is LS-TTL compatible logic inputs, current sense, monostable, thermal shutdown and a power H-bridge output stage. Two UC3770As and a few external components form a complete micro-processor-controllable stepper motor power system. Unlike the UC3717, the UC3770A require external high-side clamp diodes. The UC3770A is identical in all regards except for the current sense thresholds. Thresholds for the UC3770A are identical to those of the older UC3717 permitting drop-in replacement in applications where high-side diodes are not required.
