Product details

Two-rail watchdog in a SOT-23-6 package

Thresholds and timing for the BOM

The 1.8V fixed threshold covers the core rail of many low-voltage MCUs and FPGAs, while the adjustable channel lets you monitor a second supply — say 3.3V or 5V I/O — without adding a second supervisor IC. The 5µs propagation delay means the reset pin pulls low fast enough to hold the processor in reset before a brownout corrupts the program counter. Housed in a SOT-23-6 package with 0.95 mm pitch, the part reflows cleanly on a standard FR-4 board.

Industrial temperature grade for the shop floor

The SOT-23-6 package's low thermal mass means it tracks the ambient quickly — no warm-up delay before the reset thresholds are valid.

Frequently asked questions

What is the reset timeout of the TPS3806J20DBVR?

The TPS3806J20DBVR has a typical propagation delay of 5µs from the supply crossing the threshold to the reset output asserting. There is no fixed reset timeout period — the reset de-asserts once both monitored voltages rise above their thresholds.

Can the TPS3806J20DBVR monitor two voltages simultaneously?

Yes. The TPS3806J20DBVR monitors two voltages simultaneously — one fixed at 1.8V and a second adjustable channel. The open-drain reset output asserts if either voltage falls below its respective threshold.
