Parameter
Short Description
Function
Periodicity
Monitoring of VCC1, VCC2, VEE2.
Continuous.
Action in case of failure event 1. Emergency (Regular) Turn-off Sequence.
2. Error Flag PER.RST1 (UVLO1) or SER.UVLO2ER or OVLO2ER or UVLO3ER or
OVLO3ER) is set.
3. Assertion of signal NRST/RDY (UVLO1 only) or NFLTB.
Programmability
Yes (OVLO2and OVLO3).
In-System Testability
Yes (see Chapter 3.5.8).
In order to ensure a correct switching of the IGBT, the device supports an undervoltage lockout (UVLO)
function for VCC1, VCC2, VEE2, and an overvoltage lockout (OVLO) function for VCC2 and VEE2 (Figure 21).
