TEA3717DP

步进电机驱动器 STEPPER MOTOR DRIVER

DESCRIPTION

The TEA3717 is a bipolar monolithic integrated circuit intended to control and drive the current in one winding of a bipolar stepper motor. The circuit consists of an LS-TTL compatible logic input, a current sensor,a monostable and an outputstage with built in protection diodes.Two TEA3717 and a few external components form a complete control and drive unit for LS-TTL or microprocessor-controlled stepper motor systems.
