Overview
The UCC37322DGNR is a high-speed, single-channel gate driver produced by Texas Instruments. It belongs to the UCC2732x/UCC3732x family of drivers, which are designed to deliver high peak drive currents in an industry-standard pinout. This driver is capable of driving the largest MOSFETs, making it suitable for systems that require extreme Miller current due to high dV/dt transitions. The UCC37322DGNR features a noninverting logic option and includes an enable function for better control over the driver's operation.
