UCC27325DGN

Gate Driver Overview

The UCC27325DGN is a dual high-speed low-side power MOSFET driver from Texas Instruments, housed in an 8-pin MSOP PowerPAD package. It delivers a peak output current of 4 A and operates within a supply voltage range of 4 V to 15 V. The device features typical rise and fall times of 20 ns with a 1.8-nF load, and propagation delays of 25 ns (input falling) and 35 ns (input rising). It draws a supply current of 0.3 mA and functions reliably across an operating temperature range of -40°C to 85°C.

Gate Driver Feature Summary

• Delivers high-current drive capability of ±4 A at the Miller plateau region for efficient switching.
• Features hysteretic logic inputs that are TTL/CMOS compatible and independent of supply voltage.
• Utilizes a unique BiPolar and CMOS hybrid output stage for efficient sourcing and sinking at low voltages.

Gate Driver Applications

• Switch Mode Power Supplies
• DC/DC Converters
• Motor Controllers

Gate Driver Procurement Notes

Verify the specific suffix 'RG4' against the requested part number, as it indicates tape-and-reel packaging which differs from the standard tube configuration. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement decisions.

Gate Driver Selection Notes

Select this component when a dual low-side driver with 4 A peak current is required in a thermally enhanced MSOP package. Ensure the application does not exceed the 15 V maximum supply voltage or the 85°C junction temperature limit defined in the datasheet specifications.

Gate Driver Part Context

This device belongs to the UCC3732x family of dual high-speed low-side MOSFET drivers. It shares pinout compatibility with other variants in the series, such as the UCC37323 and UCC37324, differing primarily in internal logic configurations like inverting or non-inverting outputs.

Gate Driver Replacement Considerations

The UCC37325DGN is functionally equivalent to the UCC27325DGN. Verify package integrity and thermal performance requirements when substituting between these identifiers.
