Half-Bridge Gate Driver 1200 V 2.5 A Source/3.4 A Sink

ON Semiconductor 

Half-Bridge Gate Driver

1200 V 2.5 A Source/3.4 A Sink

FAD8253

Description

The FAD8253 is a monolithic half−bridge gate driver IC designed

for driving high voltage, high speed and high power IGBTs up to

+1200 V. The FAD8253 employs ON’s high−voltage process and

common−mode noise canceling technique to provide stable operation

of high−side driver under high dv/dt noise circumstances. The gate

driver includes UVLO circuits tailored to IGBT threshold for both

high side and low side outputs to prevent malfunction when VDD and

VBS are lower than the specified threshold voltage.

The FAD8253 offers a built−in low−side current detection circuitry

with an additional provision for soft shutdown (for low side) during

overcurrent or short−circuit conditions. The driver can provide

adequate protection during short−circuits by turning off its outputs

while simultaneously generating a fault output for fault reporting

purposes. The driver also provides additional flexibility by providing

a shutdown pin to disable driver outputs externally.
