2A/4A 双通道隔离式栅极驱动器 - UCC21220
 

描述

The UCC21220 device is an isolated dual-channel gate driver with 4-A peak-source and 6-A peak-sink current. It is designed to drive power MOSFET, IGBT, and GaN transistors with the best-in-class dynamic performance.

The device can be configured as two low-side drivers, two high-side drivers, or half-bridge drivers. Two outputs can be paralleled to form a single driver which doubles the drive strength for heavy load conditions without internal shoot-through due to the best-in-class delay matching performance.

The input side is isolated from the two output drivers by a 3.0-kVRMS isolation barrier, with a minimum of 100-V/ns common-mode transient immunity (CMTI).

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

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