UCC21222 - 4-A, 6-A, 3.0-kV(RMS) Isolated Dual-Channel Gate Driver With Dead Time

The UCC21222 device is an isolated dual channel gate driver withprogrammable dead time. It is designed with 4-A peak-source and 6-A peak-sink current to drivepower MOSFET, IGBT, and GaN transistors.

The UCC21222device 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 forheavy load conditions without risk of internal shoot-through.

The input side is isolated from the two output drivers by a3.0-kV_RMS isolation barrier, with a minimum of 100-V/ns common-modetransient immunity (CMTI).

Resistor programmable dead time gives the capability to adjust dead time for systemconstraints 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 deglitchfilter 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.
