UCC37322DR

Gate Driver Overview

The UCC37322DR is a single high-speed low-side MOSFET driver manufactured by Texas Instruments. It features a peak output drive current of 9 A and operates within a supply voltage range of 4 V to 15 V. The device supports both inverting and non-inverting logic configurations with CMOS or TTL input compatibility. Key electrical parameters include a typical rise time of 35 ns and a fall time of 20 ns. It is housed in an 8-pin SOIC package and is rated for an operating temperature range of -40°C to +105°C.

Gate Driver Feature Summary

• Provides high-current 9-A peak drive capability for rapid MOSFET switching
• Includes a dedicated enable pin for power management control
• Supports flexible logic input compatibility with CMOS and TTL standards

Gate Driver Applications

• Low-side gate driving in DC-DC converter topologies
• Motor control systems requiring fast switching speeds
• Industrial power supply designs utilizing low-side MOSFETs

Gate Driver Procurement Notes

Verify the specific suffix 'DR' corresponds to the tape-and-reel packaging format rather than tube packaging when sourcing. Confirm the extended industrial temperature rating (-40°C to +105°C) matches your thermal design requirements, as other variants may have different limits. Ensure the SOIC-8 footprint aligns with your PCB layout specifications.

Gate Driver Selection Notes

Select this component when a single-channel low-side driver with high peak current is required. It is suitable for applications needing fast switching transitions to minimize conduction losses. Consider the enable feature if system-level power gating is necessary. Compare against the UCC27322 series for potential pin-compatible alternatives with similar performance characteristics.

Gate Driver Part Context

This part belongs to the UCC3732x family of high-speed MOSFET drivers from Texas Instruments. These devices are designed to replace discrete driver solutions, offering improved performance and reduced board space. The family typically includes variants with different temperature ratings and packaging options, such as the PDIP and SOIC packages.

Gate Driver Replacement Considerations

The UCC27322DR is a direct functional replacement with identical pinout and extended temperature range. Verify that the substitute part maintains the same 9-A drive current and SOIC-8 package dimensions to ensure mechanical compatibility.
