Pin Configuration VRFE(t) = 3.3V * e-t/RC < VIN,TH- +3.3V CRCIN < 500ns / ( - ln (VIN,TH- / 3.3V) * RRFE_ON) Consider VIN,TH- of 0.8V and RRFE_ON of 50ohm, CRCIN RRCIN 6 L- should be less than 7nF. It is also suggested to use a 1 To Microcontroller 3 2 RRCIN of between 0.5MΩ and 2MΩ. 6 RFE IM CRCIN Input Noise HIN filter Deadtime & Shoot-Through

filter VDD Under- The Fault function allows the IPM to report a Fault COM voltage detection condition to the microncontroller by pulling the RFE pin low in one of two situations. The first is an under- voltage condition on VDD and the second is when the ITRIP ITRIP pin sees a voltage rising above V ITRIP IT,TH+. Noise filter The programmable fault clear timer function provides a means of automatically re-enabling the module operation a preset amount of time (TFLT-CLR) after the fault condition has disappeared. Figure 6 RFE Noise filter shows the RFE-related circuit block diagram inside the IPM. The length of TFLT-CLR can be determined by using the formula below. VRFE(t) = 3.3V * (1 – e-t/RC)

TFLT-CLR = -RRCIN * CRCIN * ln(1-VIN,TH+/3.3V) For example, if RRCIN is 1.2MΩ and CRCIN is 1nF, the TFLT-
