Low-Voltage Supervisory Circuit with Watchdog and Manual Reset TPV6823

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

◉ It also has an on-chip watchdog timer, which can give out a reset signal if the microprocessor fails to strobe the 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 the SOT23-5 package and typically consumes only 2.2 μA, suitable for.
