Hello,
I have to design the High Voltage (800V) Heater System using Low-Side Switch circuit with IGBT
This system is similar to PTC Heater for HVAC.
Can this system be desinged using UCC27511A-Q1 for low side driver ?
If UCC27511A-Q1 is not suitable for PTC heater design, please recommend another driver.
Hi Chang-Hee,
I think UCC27511A-Q1 could be used if MCU is referred to the 400V/800V bus ground. UCC5350-Q1 can be used if isolation is needed.
