The ISO5452 is a 5.7-kVRMS, reinforced isolated gate driver for IGBTs and MOSFETs with split outputs, OUTH and OUTL, providing 2.5-A source and 5-A sink current. The input side operates from a single 2.25-V to 5.5-V supply. The output side allows for a supply range from minimum 15 V to maximum
30 V. Two complementary CMOS inputs control the output state of the gate driver. The short propagation time of 76 ns assures accurate control of the output stage.

An internal desaturation (DESAT) fault detection recognizes when the IGBT is in an overcurrent condition. Upon a DESAT detect, a Mute logic immediately blocks the output of the isolator and initiates a soft-turn-off procedure which disables OUTH, and pulls OUTL to low over a time span of
2 μs. When OUTL reaches 2 V with respect to the most negative supply potential, VEE2, the gate driver output is pulled hard to VEE2 potential, turning the IGBT immediately off.
