The TPV706 is a supervisory circuit that monitors power supply voltage levels and provides a poweron reset signal.

A watchdog monitor is provided, which is activated if the watchdog input doesn’t toggle within 1.6 sec.

A reset signal can also be asserted by an external manual reset input.

In addition, there is a power fail detector with 1.25V threshold, which can be used to monitor an additional power supply. The reset periods are fixed at 200 ms (typical).

The TPV706 is available in a 8-lead SOP package and typically consumes only 4 μA, suitable for use in low power, portable applications.
