TPV6823 Reset Ics with Watchdog|3peak

　　The TPV6823 is a supervisory circuit that monitors power supply voltage levels and provides a power-on reset signal.

 

　　It also has on-chip watchdog timer,which can give out a reset signal if the microprocessor fails to strobe watchdog timer within a preset timeout period.

 

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

 

　　The reset and watchdog timeout periods are fixed at 200 ms(typical)and 1.6 sec(typical),respectively.

 

　　The TPV6823 is available in a 5-lead SOT-23 package and typically consumes only 2.2μA,suitable for use in low power,portable applications.
