TPV821 - Low Voltage Supervisory Circuit

General Description

The TPV821 is a supervisory circuit that monitors power supply voltage levels and provides a power-on reset signal.

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

The reset periods are fixed at 200 ms (typical).

Key Features

  • Precision low voltage monitoring.
  • 200 ms (typical) reset timeout.
  • Manual reset input.
  • Reset output stage.
  • Open Drain Active-low output (TPV821).
  • Low power consumption: 2.2 μA.
  • Guaranteed reset output valid to VCC = 1 V.
  • Power supply glitch immunity.
  • Specified from.
  • 40°C to +125°C.
  • 5-lead SOT-23-5 package and 4-lead SOT-143 package.
