UCC27322DRG4

Gate Driver Overview

The UCC27322DRG4 is a single-channel, low-side MOSFET gate driver manufactured by Texas Instruments. It provides a peak output current of 9 A for both sourcing and sinking. The device operates within a supply voltage range of 4 V to 15 V and supports CMOS and TTL logic inputs. It features an enable pin for power management and is housed in an 8-SOIC package with a lead-free RoHS-compliant construction. The operational temperature range extends from -40°C to +105°C.

Gate Driver Feature Summary

• Delivers high-speed switching performance with 9-A peak drive capability for efficient MOSFET control.
• Includes an integrated enable pin to manage power consumption and control driver state.
• Accepts standard digital logic signals through compatible CMOS and TTL input thresholds.

Gate Driver Applications

• Low-side switching in DC-DC converter topologies
• Motor control circuits requiring direct MOSFET gate driving
• Power supply designs utilizing single-ended low-side configurations

Gate Driver Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and environmental adherence during procurement. Confirm the SOIC-8 package dimensions match the target PCB footprint. Ensure the component meets the required operating temperature range for the intended application environment before finalizing orders.

Gate Driver Selection Notes

Select this component when a single low-side driver with high peak current is required. It is suitable for applications needing fast switching speeds and compatibility with standard logic levels. Consider the thermal dissipation capabilities of the SOIC package relative to the expected duty cycle and ambient conditions.

Gate Driver Part Context

This part belongs to the UCC2732x series of high-speed MOSFET drivers from Texas Instruments. The series includes variants with different channel counts and current ratings. The UCC27322 specifically focuses on single-channel low-side applications, offering a balance of speed and drive strength for general-purpose power electronics.

Gate Driver Replacement Considerations

The UCC27322D serves as a non-RoHS compliant alternative within the same family. Verify that any substitute maintains the 9-A output current and 8-SOIC package form factor to ensure mechanical and electrical compatibility without redesigning the circuit board.
