Application Scenarios & Design Considerations

Quintuple Voltage Monitor

Alternative Part Number

  • MAX6710HEUS+T --: Supervisory circuit with similar reset threshold and active-low push-pull output in a SOT-23 package, a common cross for ISL88031 voltage supervisors.
  • TPS3808G01DBVR --: Adjustable-threshold voltage supervisor with programmable delay in SOT-23-6, functionally comparable to the ISL88031 supervisor family.
  • MCP1316T-29FE/OT --: Low-power voltage supervisor with fixed reset threshold and active-low output in SOT-23-5, suitable as a drop-in functional replacement.
  • TPS3700HEO2DDFR --: Window voltage supervisor with adjustable thresholds and open-drain reset, functionally comparable to the ISL88031 supervisor.
  • ADM6710HARJZ-REEL7 --: Multi-voltage supervisor with reset output, similar monitoring role and package options, suitable as a functional replacement.
