LP3470 - Voltage Supervisor

General Description

The LP3470 device is a micropower voltage supervisory circuit designed to monitor voltages within 1% of reset threshold over temperature.

It provides maximum adjustability for power-on-reset (POR) and supervisory functions.

Key Features

  • 1 5-Pin SOT-23 Package.
  • Open-Drain Reset Output.
  • Programmable Reset Time-Out Period Using an External Capacitor.
  • Immune to Short VCC Transients.
  • ±1% Reset Threshold Accuracy Over Temperature.
  • Low Quiescent Current (16 µA typical).
  • Reset Valid Down to VCC = 0.5 V 2.
