Description

The TPV811/812 is a supervisory circuit that monitors

power supply voltage levels and provides a power-on reset

signal.

A reset signal can also be asserted by an external manual

reset input.

The reset periods are fixed at 200 ms (typical).

The TPV811/812 is available in a 5-pin SOT-23-5 package

and a 4-pin SOT-143 package, typically consumes only 2.2

μA, suitable for low-power and portable applications.
