IRS233(0,2)(D)(S&J)PbF
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 CC and the second is if the ITRIP pin recognizes
a fault. Once the fault condition occurs, the FAULT pin is internally pulled to V SS and the fault condition is latched. The fault
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 CC .
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 0 , R 1 , and R 2 )
connected to ITRIP as shown in Figure 9, and the ITRIP threshold (V IT,TH+ ). The circuit designer will need to determine the
maximum allowable level of current in the DC- bus and select R 0 , R 1 , and R 2 such that the voltage at node V X reaches the
over-current threshold (V IT,TH+ ) at that current level.
V IT,TH+ = R 0 I DC- (R 1 /(R 1 +R 2 ))
Figure 9: Programming the over-current protection
For example, a typical value for resistor R 0 could be 50 m . The voltage of the ITRIP pin should not be allowed to exceed 5
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 3 and R 4 . As the temperature changes, the resistance of the
thermistor will change; this will result in a change of voltage at node V X . The resistor values should be selected such the
voltage V X should reach the threshold voltage (V IT,TH+ ) of the ITRIP functionality by the time that the maximum allowable
temperature is reached. The voltage of the ITRIP pin should not be allowed to exceed 5 V.
When using both the over-current protection and over-temperature protection with the ITRIP input, OR-ing diodes (e.g.,
DL4148) can be used. This network is shown in Figure 11; the OR-ing diodes have been labeled D 1 and D 2 .
