DESCRIPTION
The L6232B is a triple half bridge driver intended
for use in brushless DC motor applications. This
part can be used to form the power stage of a
three-phase, brushless DC motor control loop,
and is especially useful for disk drive applications.
Power drivers are Integrated DMOS transistors
and feature fast recirculating diodes as an integral

part of their structure. The logic inputs are TTL-
level compatible, with internal pull-up, allowing in-
terfacing to open collector outputs. All necessary
circuitry to perform PWM and linear motor speed
control is included. A central charge pump is util-
ized to drive the upper DMOS transistors, and
also to power the braking function. The L6232B is
packaged in PLCC28.
