CIRCUIT DESCRIPTION
L6234 is a triple half bridge designed to drive
brushless DC motors.
Each half bridge has 2 power DMOS transistors
with R
controlled independently by means of the 3 inputs
IN1, IN2, IN3 and the 3 inputs EN1, EN2, and

EN3. An external connection to the 3 common
low side DMOS sources is provided to connect a
sensing resistor for constant current chopping ap-
plication.
The driving stage and the logic stage are de-
signed to work from 7V to 52V.
