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.
