TPV706 Low Voltage Supervisory Circuit with Watchdog

　　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 4μA,suitable for use in low power,portable applications.
