Product details

1.71V reset supervisor for 1.8V rails

When the supply drops below this threshold, it asserts a reset signal — active-low, push-pull output — and holds it for a minimum of 120ms after the rail recovers. That delay gives the downstream processor time to finish its power-up sequence before the reset releases.

Housed in a 5-pin SC-70-5 (SOT-353) package, this is a surface-mount part with a 0.65mm pitch — small enough to tuck next to the monitored rail without eating board space.

No last-time-buy window, no end-of-life notice on the books.

Frequently asked questions

What is the reset threshold voltage of TPS3801E18DCKR?

Design engineers need to confirm it matches the supervised voltage rail (1.71V) for proper system reset.

Where can I buy TPS3801E18DCKR?

Sourcing buyers need reliable distributors to purchase the part with minimal lead time.

Is TPS3801E18DCKR in stock?

Immediate availability is critical for production schedules and avoiding line stoppages.

What is the package type of TPS3801E18DCKR?

Maintenance techs and designers must ensure the package (SC-70-5) fits the board layout.

What is the output type of TPS3801E18DCKR?

The push-pull active-low output must be compatible with the reset input of the target microcontroller.

Is TPS3801E18DCKR obsolete or EOL?

Brokers and buyers need to know lifecycle status to avoid sourcing obsolete parts that may be hard to find later.
