UCC57108BDR

Overview

The UCC57108BDR is a low-side gate driver from Texas Instruments designed for high-power automotive applications. It features a single channel with 3A peak source and sink current, supporting IGBT and SiC devices. The device operates within a bias voltage range of 8.5V to 26V and includes desaturation protection with programmable delay. Key electrical parameters include an 8ns rise time, 14ns fall time, and a maximum propagation delay of 50ns. It functions reliably across a junction temperature range of -40°C to +150°C.

Feature Summary

Integrated desaturation protection with fault reporting and soft shutdown capability
Robust input handling capable of tolerating negative voltages up to -5V
Self-protected design incorporating thermal shutdown functionality
Wide bias supply voltage range suitable for bipolar voltage configurations

Applications

HEV/EV PTC heaters
Traction inverters
Active discharge circuits
Motor drivers

Procurement Notes

Verify the specific suffix BDR corresponds to the SOIC-8 surface-mount package configuration. Confirm that the component meets the required operating temperature range for the intended application environment. Ensure compatibility with the system's logic levels and bias voltage specifications before integration into the final design.

Selection Notes

Select this component when driving low-side IGBT or SiC switches requiring moderate speed and integrated fault protection. The non-inverting configuration simplifies control interface design. Consider the wide operating temperature range and robust input tolerance for systems experiencing significant ground bounce or noise.

Part Context

This part belongs to the UCC5710x family of high-speed low-side gate drivers. It is engineered for demanding power electronics environments, offering a balance of drive strength and protection features. The SOIC-8 package provides a compact footprint suitable for dense PCB layouts in automotive and industrial power modules.
