CIRCUIT DESCRIPTION
L6234 is a triple half bridge designed to drive
brushlessDC motors.
Each half bridge has 2 power DMOS transistors
with R
ds
ON = 0.3
.
The 3 half bridges can be
controlled independentlyby meansof 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.
