Hello,
I want to drive two brushed DC motors (about 3A RMS each) using DRV8412 with basic left/right/stop control, no PWM. There is a section in the datasheet named "Bootstrap Capacitor Under Voltage Protection" saying that I need to increase bootstrap capacitance when using low frequency PWM. Since I want to use fixed levels, it will trigger under voltage protection. Will the DRV8412 work with simple logic drive? How big should then the bootstrap capacitor be? What will happen if I apply 100% duty cycle - will it drive the motor close to that duty cycle?
Thanks
