UCC21220A - 4-A, 6-A, 3.0-kVRMS Isolated Dual-Channel Gate Driver

The UCC21220 and UCC21220A devices areisolated dual-channel gate driver with 4-A peak-source and 6-A peak-sink current. It is designed to drive power MOSFET, IGBT, and GaNtransistors with the best-in-class dynamic performance.

The devices can be configured as two low-side drivers, two high-side drivers, orhalf-bridge drivers. Two outputs can be paralleled to form a single driver which doubles the drivestrength for heavy load conditions without internal shoot-through due to the best-in-class delaymatching performance.

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).

Protection features include: DIS pin shuts down both outputs simultaneously when it isset high; INA/B pin rejects input transient shorter than 5-ns; both inputs and outputs canwithstand –2-V spikes for 200-ns, all supplies have undervoltage lockout (UVLO), and active pulldown protection clamps the output below 2.1-V when unpowered or floated.

With these features, the device enables high efficiency, high power density, androbustness in a wide variety of power applications.
