TEA3718DP
DESCRIPTION
The TEA3718 and TEA3718Sare bipolar monolithic integrated circuits intended to control and drive the current in one winding of a bipolar stepper motor. The circuits consist of an LS-TTL patible logic input, a current sensor, a monostable and an output stage with built-in protection diodes. Two TEA3718 or TEA3718S and a few external ponents form a plete control and drive unit for LS-TTL or microprocessor-controlled stepper motor systems. PIN CONNECTIONS (top views)
