ISO5852S
SLLSEQ0A –AUGUST 2015–REVISED SEPTEMBER 2015
ISO5852S High-CMTI 2.5-A / 5-A Isolated IGBT, MOSFET Gate Driver
with Split Outputs and Active Safety Features
1 Features
3 Description
The ISO5852S 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.

Soft Turn-Off (STO) during Short Circuit
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.

When desaturation is active, a fault signal is sent
across the isolation barrier pulling the FLT output at
the input side low and blocking the isolator input.
Mute logic is activated through the soft-turn-off
period. The FLT output condition is latched and can
be reset only after RDY goes high, through a low-
active pulse at the RST input.
