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-lead SOT-23-5 package and 4-lead SOT-143 package. And typically consumes only 2.2 μA, suitable for use in low power,

portable applications.
