Description

General part information

UCC21540A-Q1 Series

The UCC21540-Q1 device is an isolated dual channel gate driver with programmable dead time and wide temperature range. This device exhibits consistent performance and robustness under extreme temperature conditions. It is designed with 4 A peak-source and 6 A peak-sink current to drive power MOSFET, IGBT, and GaN transistors.

The UCC21540-Q1 can be configured as two low-side drivers, two high-side drivers, or a half-bridge driver. The input side is isolated from the two output drivers by a 5.7-kVRMS isolation barrier, with a minimum of 125-V/ns common-mode transient immunity (CMTI).

Protection features include: resistor programmable dead time, disable feature to shut down both outputs simultaneously, and negative voltage handling for up to –5-V spikes for 50 ns on input pins. All supplies have UVLO protection.
