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.
