ISO5451 High-CMTI 2.5-A / 5-A Isolated IGBT, MOSFET Gate Driver

with Active Safety Features

1 Features

3 Description

The ISO5451 is a 5.7-kV_RMS, reinforced isolated gate

•

50-kV/μs Minimum and 100-kV/μs Typical

Common-Mode Transient Immunity (CMTI)

at V_CM= 1500 V

driver for IGBTs and MOSFETs with 2.5-A source

and 5-A sink current. The input side operates from a

single 3-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.

•

2.5-A Peak Source and 5-A Peak Sink Currents

Short Propagation Delay: 76 ns (Typ),

110 ns (Max)

•

2-A Active Miller Clamp

Output Short-Circuit Clamp

An internal desaturation (DESAT) fault detection

recognizes when the IGBT is in an overload

condition. Upon a DESAT detect the gate driver

output is driven low to V_EE2potential turning the IGBT

immediately off.

Fault Alarm upon Desaturation Detection is

Signaled on FLT and Reset Through RST

•

Input and Output Under Voltage Lock-Out (UVLO)

with Ready (RDY) Pin Indication

Active Output Pull-down and Default Low Outputs

with Low Supply or Floating Inputs

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. The

FLT output condition is latched and can be reset

through a low-active pulse at the RST input.

•

3-V to 5.5-V Input Supply Voltage

15-V to 30-V Output Driver Supply Voltage

CMOS Compatible Inputs

When the IGBT is turned off during normal operation

with bipolar output supply, the output is hard clamp to

V_EE2. If the output supply is unipolar, an active Miller

clamp can be used, allowing Miller current to sink

across a low impedance path preventing IGBT to be

dynamically turned on during high voltage transient

conditions.
