Overtemperature Hardware Protection Circuit

A temperature protection circuit is implemented for IGBT Q4, as shown in Figure 26, connecting NTC to ITRIP

pin through a resistor divider. The default temperature threshold is setting is 100°C. When the IGBT Q4 case

temperature is higher than 100°C, the OTP1 value will be higher than the ITRIP positive going threshold value,

and then the gate driver will be turn off issuing a fault signal thorugh RFE pin. The fault signal will be read by

the other two inverter gate drivers causing the turn off of all inverter stage.
