UCC37325DGNR

The UCC37325DGNR from Texas Instruments is a high-speed dual low-side power MOSFET driver. It delivers ±4A source and sink peak current, making it effective for driving MOSFETs at the Miller Plateau Region. The device features a Bi-CMOS output architecture and a unique BiPolar and MOSFET hybrid output stage for efficient current sourcing and sinking, even at low supply voltages.

Key electrical specifications include a supply voltage range of 4.5V to 15V, with typical rise and fall times of 20ns and 15ns respectively at a 1.8nF load. Propagation delay is rated at 35ns for rise and 25ns for fall. The input thresholds are based on TTL and CMOS, independent of the supply voltage, and offer wide input hysteresis for excellent noise immunity.

This driver is available in an 8-pin MSOP-PowerPAD package, which significantly lowers thermal resistance for improved long-term reliability. The industry-standard pin-out and TTL/CMOS inputs independent of supply voltage simplify integration into various designs. Applications include switch-mode power supplies, DC-DC converters, solar inverters, and motor control systems.

The UCC37325DGNR offers two independent channels, each capable of driving N-Channel or P-Channel MOSFETs. The input types include both inverting and non-inverting options, providing flexibility for different circuit configurations. Its low-side driven configuration is suitable for a wide range of power management applications.
