Key Features

  • ±1.25% Precision Voltage Threshold
  • SOT143 Package
  • Low Cost
  • < 5µA Typical Supply Current
  • Open-Drain Output (MAX836)
    Push-Pull Output (MAX837)

Applications/Uses

  • Battery-Powered Systems
  • Load Switching
  • Precision Battery Monitoring
  • Threshold Detectors

Description

The MAX836/MAX837 micropower voltage monitors contain a 1.204V precision bandgap reference and a comparator in a SOT143 package. The MAX836 has an open-drain, N-channel output driver, while the MAX837 has a push-pull output driver. Two external resistors set the trip threshold voltage.
