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.
