DESCRIPTION

· The TPV6823 is a supervisory circuit for monitoring power supply voltage levels and providing a power-on reset signal.

· It includes an on-chip watchdog timer that issues a reset signal if the microprocessor fails to strobe within a preset timeout period.

· Features an external manual reset input for asserting a reset signal.

· Available in a SOT23-5 package, consuming only 2.2 μA, ideal for low-power and portable applications.

FEATURES

· Precision low voltage monitoring.

· Reset timeout of 200 ms (typical).

· Watchdog timer with a 1.6-sec timeout.

· Manual reset input and push-pull active-low reset output stage.

· Low-power consumption: 2.2 μA.

· Guaranteed reset output valid to VCC = 1 V.

· Power supply glitch immunity.

· Operational from −40°C to +125°C.

APPLICATIONS

· Microprocessor systems.

· Computers and controllers.

· Intelligent instruments.

· Portable equipment.
