3 Description

The ISO5852S-Q1 device 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 provides 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-turnoff procedure which disables the

OUTH pin and pulls the OUTL pin to low over a time

span of 2 μs. When the OUTL pin reaches 2 V with

respect to the most-negative supply potential, VEE2,

the gate-driver output is pulled hard to the VEE2

potential, turning the IGBT immediately off.
