Product details

What this part is and where it fits

The UC3910DTR is a supervisor IC for power supply support — the kind of part that monitors a voltage rail and asserts a reset or fault signal when the supply drops outside a tolerance window. It is the watchdog between the regulator and the downstream logic, sized for board-level supervision in systems that need a clean, deterministic power-on and power-off sequence. ROHS3 compliant, so it clears the EU material restrictions without an exemption review.

Lifecycle and sourcing posture

The UC3910DTR carries an Active product status — no last-time-buy clock ticking, no EOL notice to track. That means it can be specified into a new BOM without planning an early migration.

Frequently asked questions

What is the UC3910DTR used for?

The UC3910DTR is a supervisor IC for power supply support, used to monitor voltage rails and assert reset or fault signals in systems requiring reliable power sequencing.

What is the UC3910DTR replacement or equivalent?

No official replacement or second-source alternate is recorded for the UC3910DTR. For a functionally similar reset IC, the TLV803EA29VDBZR (active-low, open-drain output, 130 ms timeout) is a common cross-shop candidate, but verify pin compatibility and threshold voltage against your rail before substituting.
