UCC5390-Q1: PWM Interlock of IN+ and IN– when use UCC5390-Q1 + UCC21750-Q1 for a Half Bridge

Part Number: UCC5390-Q1
Other Parts Discussed in Thread: UCC21750-Q1,

Hi Team,

UCC21750-Q1 features the PWM interlock for IN+ and IN– pins, which can be used to prevent the phase leg shoot through issue.

But customer want to use UCC5390-Q1 is upper leg to save cost. Could they tie IN+ / IN- of 21750 & 5390 directly for PWM interlock?

The switching frequency is 65kHz.

Thank you!
