UCC21750: Connecting RST/EN line of multiple ICs

Part Number: UCC21750

Can i connect all 6 RST/EN lines ( using 6 drivers for a 3 phase inverter) so that i can  use a single microcontroller output pin to reset/enable all together.

    Hi David,

    Yes, you can implement a global RST/EN signal by connecting all of the inputs together.

    You should populate separate filtering capacitors at each chip's RST/EN pin close to the IC in case of noise. This could be minimum of 100pF.
