3 Description
The ISO5452 is a 5.7-kV_RMS, 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, V_EE2, the gate driver
output is pulled hard to V_EE2 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.
