Overview
The UCC5390ECQDWVQ1 is a single-channel, isolated gate driver designed by Texas Instruments for driving power semiconductor devices such as MOSFETs, IGBTs, and SiC MOSFETs. This device is particularly suited for automotive applications, given its AEC-Q100 qualification and functional safety quality management. It features a high isolation rating of up to 5kVRMS and is available in an 8-pin DWV (SOIC-8) package with 8.5mm creepage distance.
The UCC5390ECQDWVQ1 offers robust performance with 10A peak source and sink current, making it ideal for applications requiring high drive strength and reliability. The device includes advanced features such as undervoltage lockout (UVLO) for both input and output supplies, and it supports bipolar and unipolar supply configurations. The isolation barrier is implemented using high-voltage SiO2-based capacitors, ensuring long-term reliability and high common-mode transient immunity (CMTI).
