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 2.2μA,suitable for use in low power,portable applications.
