hello all, i have built the dc to ac converter using two ir2214 ic and 1200v rating mosfet,i have connect sy_fault and fault/sd pin to high logic and fault_clear pin to combination of RC to provide high logic for particular microsec and then it provides the low logic to fault_clear pin. till this the circuit is working fine but now i want it with the desaturation protection which can be done using the three pins namely sy_fault, fault/sd and fault_clear pins to microcontroller.
i need help in doing that connections as i am not apple to understand the bidirectional pins(sy_fault and fault/sd pin) which operates as input and output both.below is my circuit connection where pin 3 is made on for few millisec via RC circuit for fault_clear.
