... LB11690/LB11690H Function Description 1. Output Drive Circuit This IC was designed assuming that n-channel FETs would be used in both the low and high side output circuits. Direct PWM drive was adopted as the drive method 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 output on duty. The output PWM switching is performed on the low side output circuits connected to the UL, VL, and WL pins ...
