Overview
The UCC37322D, manufactured by Texas Instruments, is a high-speed, single-channel, low-side MOSFET driver. Although this product is no longer in production, it remains relevant for existing designs and as a reference for new projects. The UCC37322D is part of the UCC2732x/UCC3732x family, which delivers 9 A of peak drive current in an industry-standard pinout. This driver is designed to handle the largest MOSFETs, especially in systems requiring high Miller current due to high dV/dt transitions, thus eliminating the need for additional external circuits and reducing design complexity and assembly cost.
