UCC27614QDSGRQ1

Gate Driver Overview

The UCC27614QDSGRQ1 is an automotive-grade, single-channel low-side gate driver from Texas Instruments. It provides a typical peak drive current of 10A to rapidly switch MOSFETs, IGBTs, SiC, and GaN devices. The device operates within a supply voltage range of 4.5V to 26V and supports both inverting and non-inverting configurations. Key electrical parameters include a maximum propagation delay of 27ns, rise time of 4.5ns, and fall time of 4ns. It functions reliably across a junction temperature range of -40°C to +125°C and is housed in an 8-pin WSON package.

Gate Driver Feature Summary

• Provides high-speed switching with 10A peak output current capability for efficient power stage control.
• Features independent enable pin allowing isolated control of the power stage separate from main logic.
• Includes robust input protection handling negative voltages up to -10V to mitigate ground bounce effects.
• Integrates active pull-down MOSFET to maintain low output state during undervoltage lockout conditions.

Gate Driver Applications

• Automotive DC-DC converters
• Motor drive systems
• Solar power inverters
• Pulse transformer drivers

Gate Driver Procurement Notes

Verify the specific suffix 'DSGR' corresponds to the WSON-8 package variant when sourcing. Confirm AEC-Q100 qualification status is required for the target automotive application. Ensure the ordering part number matches the exact tape-and-reel specifications provided by the manufacturer. Cross-reference the datasheet revision date to confirm parameter consistency.

Gate Driver Selection Notes

Select this component for applications requiring a single-channel low-side driver with high current capability. It is suitable where compact board space is critical due to the small WSON footprint. Consider the 10A drive strength for driving large capacitance loads or wide-bandgap semiconductors. Verify that the 4.5V minimum supply voltage aligns with the system's available bias rails.

Gate Driver Part Context

This device belongs to the UCC27614 family of high-speed low-side gate drivers designed for demanding power electronics. The Q1 suffix indicates compliance with automotive reliability standards. It serves as a bridge between low-voltage control logic and high-power switching elements, optimizing system efficiency through reduced switching losses.

Gate Driver Replacement Considerations

Check for UCC27614DGNRQ1 (HVSSOP-8) or UCC27614QDRQ1 (SOIC-8) if package compatibility differs. Verify pinout alignment before substitution. Ensure equivalent drive current and voltage ratings are maintained for the specific circuit requirements.
