Description

The TPV706 is a supervisory circuit to monitor power supply voltage levels and provides a power-on 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 be asserted by an external manual reset input. In addition, there is a power-fail detector with a 1.25-V 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 an 8-pin SOP package and typically consumes only 4 μA, which is suitable for low-power and portable applications.
