Introduction
The MAX817/MAX818/MAX819 microprocessor (µP) supervisory circuits simplify power-supply monitoring, battery control, and chip-enable gating in µP systems by reducing the number of components required. These devices are designed for use in +5V -powered systems. Low supply current (11µA typical) and small package size make these devices ideal for portable applications. The MAX817/MAX818/MAX819 are specifically designed to ignore fast transients on VCC. Other supervisory functions include active-low reset, backup battery switchover, watchdog input, battery freshness seal, and chip-enable gating.
These devices offer two pretrimmed reset threshold voltages for ±5% or ±10% power supplies: 4.65V for the L versions and 4.40V for the M versions. The MAX817/ MAX818/MAX819 are available in space-saving µMAX packages, as well as 8-pin DIP/SO.
Features

- Uncommitted Voltage Monitor for Power-Fail or Low-Battery Warning (MAX817/MAX819)
- Manual Reset Input (MAX819)
Applications
- Battery-Powered Computers and Controllers
- Embedded Controllers
- Intelligent Instruments
- Critical µP Monitoring
- Portable Equipment
