I'm trying to design an inverter and I'm using 2 IR2110 as gate drivers but my MCU board PWM outputs are open collector, I've added a pull-up and transistor to feed IR2110 with 5V pulses but it's not working.
Here is the full bridge and gate drive I'm using:
and here is the pull-up and transistor schematic I'm using between IR2110 pwm input and mcu open collector output(ULN2003A):

Thank you for your help.
