Other Parts Discussed in Thread: TLV3601, , UCC27211
Hello Experts,
I am designing an Active bridge rectifier (Diodes replaced by FETs). In which, the voltage can go as high as +-45V which operates at 360KHz. Now to make it work, I need to detect a few on-off threshold voltages across the FETs (-75mV and -3.9mV). To scale down the voltage and make it work, I am using the below documents from TI "Dual Polarity High-Voltage Differential Input Interface for Low-Voltage Comparators Reference Design" Which works fine with the low side MOSFETs. But unfortunately, I am unable to make it work for high-side FETs.
Can you help me with how to achieve this or is there any difference amplifier that can solve this problem?
Note: As of now, the MOSFETs are off in the simulations.
Regards
Vishal.
