Description
TCA 3727 is a bipolar, monolithic IC for driving bipolar stepper motors, DC motors and other inductive loads that operate on constantcurrent. The control logic and power output stages for two bipolar windings are integrated on a single chip which permits switched current control of
motors with 0.75 A per phase at operating voltages up to 50 V.
