UCC27524DGNR

Gate Driver Overview

The UCC27524DGNR is a dual low-side power MOSFET and IGBT gate driver manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 18 V and delivers a peak output current of 5 A. The device features independent non-inverting channels with typical rise and fall times of 7 ns and 6 ns, respectively. It is housed in an 8-HVSSOP package with an exposed pad for thermal management. The component supports junction temperatures up to 140 °C and includes an enable pin for power control.

Gate Driver Feature Summary

• Dual-channel architecture providing independent low-side drive capabilities for high-speed switching applications
• Integrated enable pin functionality allows for precise power management and channel control
• Robust thermal design utilizing an exposed pad to facilitate heat dissipation in surface-mount configurations

Gate Driver Applications

• Power factor correction circuits requiring efficient low-side switching
• DC-DC converter topologies utilizing synchronous rectification
• Motor drive systems controlling low-side power switches

Gate Driver Procurement Notes

Verify the specific suffix DGNR corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 8-HVSSOP footprint matches the target PCB layout dimensions. Ensure compatibility with the intended operating temperature range and supply voltage specifications before finalizing procurement orders.

Gate Driver Selection Notes

Select this component when dual independent low-side driving is required with moderate current capacity. The HVSSOP package offers a compact solution for space-constrained designs. Consider the 5 A peak current capability against the load capacitance requirements to ensure adequate switching speeds without exceeding thermal limits.

Gate Driver Part Context

This part belongs to the UCC27524A series of high-speed gate drivers from Texas Instruments. It shares functional similarities with other members like the UCC27524DR but differs in physical packaging. The series is designed for general-purpose power management applications requiring reliable isolation between logic inputs and power switches.

Gate Driver Replacement Considerations

The UCC27524DGN is the tube-packaged equivalent of this reel-based component. Verify pinout compatibility if substituting with other SOIC or MSOP variants within the same family.
