Fault Reporting
The IRS233(0,2)(D) family provides an integrated fault reporting output. There are two situations that would cause the HVIC
to report a fault via the FAULT pin. The first is an undervoltage condition of V
a fault. Once the fault condition occurs, the FAULT pin is internally pulled to V
output stays in the low state until the fault condition has been removed by all LINx set to high state. Once the fault is removed,
the voltage on the FAULT pin will return to V
Over-Current Protection
The IRS233(0,2)(D) HVICs are equipped with an ITRIP input pin. This functionality can be used to detect over-current events
in the DC- bus. Once the HVIC detects an over-current event through the ITRIP pin, the outputs are shutdown, a fault is
reported through the FAULT pin.
The level of current at which the over-current protection is initiated is determined by the resistor network (i.e., R
connected to ITRIP as shown in Figure 9, and the ITRIP threshold (V
maximum allowable level of current in the DC- bus and select R
over-current threshold (V
For example, a typical value for resistor R
V; if necessary, an external voltage clamp may be used.
Over-Temperature Shutdown Protection
The ITRIP input of the IRS233(0,2)(D) can also be used to detect over-temperature events in the system and initiate a
shutdown of the HVIC (and power switches) at that time. In order to use this functionality, the circuit designer will need to
design the resistor network as shown in Figure 10 and select the maximum allowable temperature.
This network consists of a thermistor and two standard resistors R

When using both the over-current protection and over-temperature protection with the ITRIP input, OR-ing diodes (e.g.,
