Original TI UCC21550BQDWRQ1 Automotive Reinforced Isolation Dual-Channel Gate Driver

Description
UCC21550BQDWRQ1 is an isolated dual-channel gate driver with programmable dead time and wide temperature range. The device uses 4A peak pull current and 6A peak fill current to drive power MOSFET, SiC, GaN, and IGBT transistors.

UCC21550BQDWRQ1 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 5kVRMS isolation layer with a minimum common mode transient immunity (CMTI) of 125V/ns.
