Part Number: ISO5852S
My customer is interested in using the ISO5852 to drive a FET with a +10V Gate drive. The ISO5852 has a recommended minimum of +15V but has ABS minimum at -.3V. What would be the implications of running Vcc2 at 10V or 12V to support their application? Would that mode of operation work or would there be significant performance differences?
ISO5852S is more suitable to drive IGBTs and SIC MOSFET where VCC2 is usually higher than 15V. There is a UVLO function integrated to monitor the status of VCC2. The driver output will be disabled if the VCC2 goes below 12. That said, ISO5852S is not suitable for the apps where 10V VCC2 is used.
In reply to Xiong Li:
Thank you! That was my understanding but it is good to have it confirmed for my customer.
