UCC27523D

Gate Driver Overview

The UCC27523D is a dual-channel, low-side gate driver manufactured by Texas Instruments. It delivers high-peak current pulses of up to 5A source and 5A sink into capacitive loads. The device features rail-to-rail drive capability and an extremely small propagation delay, typically 13ns. It utilizes a design that inherently minimizes shoot-through current. The package type is SOIC-8.

Gate Driver Feature Summary

• Dual-channel architecture with matched internal propagation delays for critical timing applications
• High peak output current capability of 5A source and 5A sink
• Inherent design minimizes shoot-through current in power switches

Gate Driver Applications

• Synchronous rectifiers requiring dual-gate drives with critical timing
• Driving MOSFET power switches
• Driving IGBT power switches

Gate Driver Procurement Notes

Verify the specific suffix 'D' indicates the SOIC-8 tube package variant rather than tape-and-reel options. Confirm RoHS compliance status through official manufacturer documentation before procurement. Ensure input signal levels are compatible with the CMOS logic interface specified in the datasheet.

Gate Driver Selection Notes

Select this component when dual-channel synchronization is required for synchronous rectification or parallel switch driving. The matched propagation delays make it suitable for applications where timing skew between channels must be minimized. Verify that the 5A peak current meets the load requirements.

Gate Driver Part Context

This part belongs to the UCC2752x family of dual high-speed low-side gate drivers. The family is designed to effectively drive MOSFET and IGBT power switches. Unlike single-channel variants, this model provides two independent outputs with matched delays, enabling parallel connection for increased current drive or simultaneous control of two switches.

Gate Driver FAQ

Can the two channels be connected in parallel?

Yes, the channels can be connected in parallel to effectively increase current drive capability or to drive two switches in parallel with a single input signal.

What is the typical propagation delay?

The device features an extremely small propagation delay, typically 13ns.
