TPV6823 Low Voltage Supervisory Circuit with Watchdog and Manual Reset
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 2.2 μA, suitable for use in low power, portable applications.
