Circuit description
L6234
The L6234 is a triple half bridge designed to drive brushless DC motors. Each half bridge
has 2 power DMOS transistors with RDSon = 0.3 .
The 3 half bridges can be 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 the constant current chopping
application.
The driving stage and the logic stage are designed to work from 7 V to 52 V.
