UCC27425PE4

Gate Driver Overview

The UCC27425PE4 is a dual low-side MOSFET gate driver from Texas Instruments, housed in an 8-pin PDIP package. It provides one inverting and one non-inverting output channel with a peak drive current of ±4 A. The device operates on a supply voltage range of 4 V to 15 V and supports CMOS logic inputs independent of the supply voltage. Typical switching performance includes a 20 ns rise time and a 15 ns fall time under a 1.8-nF load. It features dedicated enable pins for each driver and is rated for operation between -40°C and +105°C.

Gate Driver Feature Summary

• Dual-channel architecture providing independent inverting and non-inverting outputs
• High-current drive capability of ±4 A optimized for Miller plateau regions
• Dedicated enable functions for precise control of driver operation
• CMOS-compatible inputs that function independently of the supply voltage

Gate Driver Applications

• Switch-mode power supplies
• DC/DC converters
• Motor controllers
• Class D switching amplifiers

Gate Driver Procurement Notes

Verify the specific suffix 'E4' against the manufacturer's official documentation to confirm RoHS compliance status and material composition details. Ensure the selected package variant matches the required PCB footprint and thermal management strategy for the target application environment.

Gate Driver Selection Notes

Select this component when a mixed polarity configuration (one inverting, one non-inverting) is required within a single package. The ±4 A drive current is suitable for medium-power MOSFETs, while the wide supply voltage range accommodates various logic levels. Consider the PDIP package constraints regarding thermal dissipation compared to surface-mount alternatives.

Gate Driver Part Context

The UCC27425PE4 belongs to the UCC2742x family of high-speed dual MOSFET drivers. This series offers industry-standard pin-outs with added enable functionality. The family includes variants with dual-inverting, dual-non-inverting, and mixed configurations, all sharing similar electrical characteristics and packaging options such as SOIC-8 and MSOP.

Gate Driver FAQ

How are the enable functions implemented?

The enable functions are implemented on pins 1 and 8, which are internally pulled up to Vdd for active-high logic. These pins can be left open for standard operation.

What is the typical propagation delay?

The typical propagation delay times are 25 ns with input falling and 35 ns with input rising.
