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.
