Description
TCA 3727 is a bipolar, monolithic IC for driving bipolar stepper motors, DC motors and
other inductive loads that operate on constant current. 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.

Pin Definitions and Functions (cont’d)
Pin No.
Function
17 (21) 1)
Inhibit input; the IC can be put on standby by low potential on this
pin. This reduces the current consumption substantially.
18 (22) 1)
Input phase 2; controls the current flow through phase winding 2. On
H-potential the phase current flows from Q21 to Q22, on L potential in
the reverse direction.
