UCC37322DGN

Gate Driver Overview

The UCC37322DGN is a single-channel, high-speed low-side MOSFET gate driver manufactured by Texas Instruments. It operates within a supply voltage range of 4 V to 15 V and delivers a peak output current of 9 A. The device features both inverting and non-inverting outputs with rise and fall times of 20 ns. Designed for surface-mount installation, it utilizes an 8-pin MSOP PowerPad package. The component supports CMOS and TTL logic inputs and includes an enable pin for control. It functions reliably across an operating temperature range from -40°C to +105°C.

• High-frequency DC-DC converter gate drive circuits
• Industrial power supply switch management
• Inverter bridge leg control systems

Gate Driver Procurement Notes

Verify the specific suffix 'DGN' corresponds to the MSOP PowerPad-8 package variant rather than standard SOIC or PDIP options. Confirm that the procurement source provides original manufacturer documentation to ensure the component meets the specified -40°C to +105°C industrial temperature rating. Cross-reference the datasheet revision date against your design requirements to guarantee compatibility with current manufacturing standards and RoHS compliance specifications.

Gate Driver Selection Notes

Select this component when a single-channel driver with high peak current capability is required for low-side applications. The inclusion of both inverting and non-inverting outputs simplifies circuit topology by eliminating external inversion stages. Ensure the application voltage does not exceed the 15 V maximum limit. Consider thermal dissipation requirements due to the PowerPad package design, which aids heat transfer but requires adequate PCB copper area for optimal performance under continuous load conditions.

Gate Driver Part Context

This part belongs to the UCC3732x series of high-speed MOSFET drivers from Texas Instruments. It serves as a surface-mount alternative to through-hole variants like the UCC37322P. The DGN suffix specifically denotes the MSOP PowerPad-8 package, distinguishing it from other package types within the same electrical family. It complements higher-channel count devices like the UCC37324 for multi-phase designs.

Gate Driver Replacement Considerations

Public confirmed substitute part numbers include UCC27322DGN, which shares identical electrical characteristics and pinout configuration. Both components offer 9 A peak current and similar timing parameters. Verify package compatibility and temperature range alignment before substitution to ensure seamless integration into existing layouts.
