3 Description

The UCC21222 device is an isolated dual channel

gate driver with programmable dead time. It is

designed with 4-A peak-source and 6-A peak-sink

current to drive power MOSFET, IGBT, and GaN

transistors.

The UCC21222 device can be configured as two low-

side drivers, two high-side drivers, or a half-bridge

driver. 5ns delay matching performance allows two

outputs to be paralleled, doubling the drive strength

for heavy load conditions without risk of internal

shoot-through.

The input side is isolated from the two output drivers

100-V/ns common-mode transient immunity (CMTI).

Resistor programmable dead time gives the capability

to adjust dead time for system constraints to improve

efficiency

and

prevent

output

overlap.

Other

protection features include: Disable feature to shut

down both outputs simultaneously when DIS is set

high, integrated deglitch filter that rejects input

transients shorter than 5-ns, and negative voltage

handling for up to -2-V spikes for 200-ns on input and

output pins. All supplies have UVLO protection.
