UCC37321D

Gate Driver Overview

The UCC37321D is a single-channel, high-speed low-side MOSFET driver manufactured by Texas Instruments. It features a peak output current of 9 A and operates within a supply voltage range of 4 V to 15 V. The device utilizes an 8-pin SOIC package with a junction temperature range of 0°C to 70°C. It incorporates hysteresis logic for noise immunity and includes an enable pin for power management control.

Gate Driver Feature Summary

Provides 9 A peak source and sink current capability for rapid MOSFET switching
Integrates hysteresis logic inputs to enhance noise immunity in high-frequency environments
Includes a dedicated enable pin to manage standby power consumption and system state

Gate Driver Applications

High-speed low-side gate driving for power MOSFETs
Industrial motor control systems requiring fast switching transitions
Power supply circuits utilizing N-channel MOSFET configurations

Gate Driver Procurement Notes

Verify the specific suffix 'D' corresponds to the 8-SOIC package variant. Confirm that the commercial temperature range (0°C to 70°C) aligns with your application requirements, as automotive or extended industrial variants may require different part numbers. Ensure compatibility with the 4V–15V supply voltage limits during design validation.

Gate Driver Selection Notes

Select this component when a single-channel low-side driver with high peak current is required. The UCC37321D is suitable for applications prioritizing switching speed and noise tolerance over wide-temperature operation. Consider alternative models if negative logic inversion or dual-channel configuration is necessary for the specific circuit topology.

Gate Driver Part Context

This device belongs to the UCC3732x series of high-speed MOSFET drivers from Texas Instruments. It is designed specifically for low-side applications, distinguishing it from high-side or half-bridge drivers. The series emphasizes fast propagation delays and robust output drive capabilities for efficient power stage control.
