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.
