描述
The MAX703/MAX704 microprocessor (µP) supervisory circuits reduce the complexity and number of components required for power-supply monitoring and battery control functions in µP systems. These devices significantly improve system reliability and accuracy compared to that obtained with separate ICs or discrete components.
The MAX703/MAX704 are available in 8-pin DIP and SO packages and provide four functions:
The MAX703/MAX704 are available in 8-pin DIP and SO packages and provide four functions:
- An active-low reset during power-up, power-down, and brownout conditions.
- Battery-backup switching for CMOS RAM, CMOS µPs, or other low-power logic circuitry.
- A 1.25V threshold detector for power-fail warning, low-battery detection, or for monitoring a power supply other than +5V.
- An active-low manual reset input.
