Upper MOSFET Floating Bootstrap Supply Pin
PWM Input Pin
When PWM voltage is higher than 2.2 V, DRVH will set to 1 and DRVL set to 0
When PWM voltage is lower than 0.8 V, DRVL will set to 1 and DRVH set to 0
When 0.8 V < PWM < 2.2 V and SW < 0, DRVL will set to 1
When 0.8 V < PWM < 2.2 V and SW > 0, DRVL will set to 0
Enable Pin
When OVP, TSD or UVLO has happened, the gate driver will pull the pin to low
