... LB11695M Functional Description 1. Output Drive Circuit The LB11695M adopts direct PWM drive to minimize power loss in the outputs. The output transistors are always saturated when on, and the motor drive power is adjusted by changing the on duty of the output. The output PWM switching is performed on the UH, VH, and WH outputs. Since the and outputs have the same output form, applications can select either low side PWM or high side PWM drive by changing the way the external output transistors are connected ...

... Constraint Protection Circuit The LB11695M is provided with a constraint protection circuit that protects the IC itself and the motor in case the motor is physically constrained (held stopped). The protection circuit turns off the outputs on one side (UH, VH, and WH) when the Hall input signals remain unchanged for a certain time in the motor drive mode. The time the Hall input signals remain unchanged (protection time) is determined by the capacitance of the capacitor connected to the CSD pin ...
