Product details

4.65V threshold supervisor — what it buys the rail

The open-drain output lets you wire-OR the reset signal with other supervisors or pull it up to a different logic rail — useful when the monitored rail and the reset-acknowledge rail are at different potentials.

Reset timeout and temperature range

The reset timeout period is adjustable or selectable via an external capacitor, giving the designer control over the delay before the part releases the reset after the supply crosses the threshold.

Package and footprint — SOT-23-6

Housed in a 6-pin SOT-23 package, the TPS3808G50DBVR fits on compact PCBs where board area is tight. The surface-mount footprint is standard and well-supported by assembly houses.

Procurement can specify it into a BOM without near-term obsolescence concern.

Frequently asked questions

What is the closest pin-compatible alternative to TPS3808G50DBVR?

The TPS3808G50DBVT is the tape-and-reel variant of the same die — electrically identical, same threshold and package. The 'R' suffix in the DBVR indicates reel packaging; the 'T' suffix in DBVT indicates tube packaging. They are interchangeable in the circuit.
