UCC27516DRSR

Gate Driver Overview

The UCC27516DRSR is a single-channel, high-speed low-side gate driver manufactured by Texas Instruments. It provides symmetrical peak output currents of 4 A for both sourcing and sinking operations. The device operates within a supply voltage range of 4.5 V to 18 V and supports both inverting and non-inverting input configurations. Key switching parameters include a typical propagation delay of 13 ns, a rise time of 9 ns, and a fall time of 7 ns. It utilizes hysteretic logic to ensure robust performance against noise. The component is housed in a WSON-6 surface-mount package and is rated for an operating temperature range from -40°C to +140°C.

Gate Driver Feature Summary

• Delivers symmetrical 4 A peak source and sink current capability for efficient power switch control
• Features hysteretic logic architecture designed to maintain stable operation under high-noise conditions
• Supports flexible interface compatibility with both inverting and non-inverting signal inputs

Gate Driver Applications

• High-frequency DC-DC converter topologies requiring fast switching speeds
• Industrial motor drive systems utilizing low-side MOSFET or IGBT control
• Inverter circuits and power factor correction modules demanding rapid transient response

Gate Driver Procurement Notes

Verify the specific ordering suffix DRSR corresponds to the WSON-6 package configuration when sourcing components. Confirm that the procurement channel provides original manufacturer documentation to validate RoHS compliance status. Ensure storage conditions align with moisture sensitivity level requirements prior to assembly processing.

Gate Driver Selection Notes

Select this component for applications requiring a single-channel low-side driver with moderate current capacity. The 4 A output rating suits standard power MOSFETs and IGBTs without excessive thermal stress. Consider the WSON-6 footprint for space-constrained designs where single-channel isolation is not required.

Gate Driver Part Context

This part belongs to the UCC275xx series of high-speed gate drivers from Texas Instruments. It complements other variants such as the UCC27517, which offers similar electrical characteristics but differs in package type. The series is engineered for general-purpose power electronics, focusing on minimizing switching losses through optimized rise and fall times.

Gate Driver Replacement Considerations

The UCC27517 serves as a functional alternative within the same family, offering identical 4 A/4 A current ratings and hysteretic logic features. Verify pinout compatibility and package dimensions (WSON-6 vs SOT-23-5) before substitution to ensure board layout alignment.
