This will fail when LO pin voltage with respect to ground less than 0.3V and more than VCC+0.3V.
#Ir2110 mosfet driver circuit diagram driver
I think low side output section of IR2110 driver circuit failed. With driving the motor, observed some spike on low side MOSFET drain and source terminal. after replacing IC its working fine with 5% duty cycle increment. But when varying duty cycle (PWM) from 0 to more than 50 percent suddenly, IR2110S driver IC getting failed sometime. When varying duty cycle from 0 to 95 present with 5 percent interval, motor running fine. I'm facing issue with IR2110S driver while driving 3 winding BLDC motor (24V, 8A rating with Hall sensor feedback) using IFR3710 MOSFET (half bridge configuration).
