UCC25800AQDGNRQ1

• Transformer Driver for Isolated Bias Supplies
• 8-Pin package, 3 X 3 Mm Body
• Production Lifecycle status, Active at the Manufacturer
• RoHS Compliant
• Open-Loop Isolated Bias Generation Without Cross-Barrier Feedback (category characteristic)

The UCC25800AQDGNRQ1 is a transformer driver for isolated bias supplies from Texas Instruments, supplied in an 8-pin package with a 3 x 3 mm body. It is in Production status with an Active manufacturer lifecycle and is RoHS compliant. A transformer driver generates the AC drive waveform for an open-loop isolated supply, producing a galvanically isolated bias rail from a single primary-side input without a feedback path across the isolation barrier.

Transformer drivers generate the isolated gate-drive and sensor bias rails needed in motor drives, solar inverters, EV onboard chargers, industrial isolated interfaces and battery management systems, where each high-side gate driver or isolated amplifier needs its own supply referenced to a floating node. They replace discrete push-pull driver circuits and often eliminate an optocoupler feedback loop. Power electronics and industrial drive designers are the usual buyers. No input voltage range, output power, switching frequency or isolation rating is recorded in this product's attributes, so confirm those against the Texas Instruments datasheet before design-in.
