**Other Parts Discussed in Thread:**UCC21530

I am looking to control a pair of Infineon IMBF170R1K0M1 SiC MOSFETs in half bridge configuration. This half-bridge will be used to switch between +20V and -1200V. DC current will be low and brief.

Your UCC21530 appears to be very fast. I'm reading thru the 44 page datasheet now....

I'm having difficulty setting up the resistors with the +20V "AND" the -1200V. Advice?

I downloaded your spice model for UCC21430 and tried to run sheet 17 with INA=5V, VCC=5V and VDD=10V. I get nothing at OUTA & OUTB. I get error messages from UCC21430 model:
