Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating  onditions for extended periods may affect device reliability.

In applications with microprocessors (Ps) that have aRESET input, the MAX7705 is functionally and socket ompatible with the TL7705, but requires no external components. It provides power-supply glitch immunity and a guaranteed power-up reset delay, while typically consuming 1/27th the power from a +5V supply.

The MAX7705 monitors the power supply in P and digital systems. The RESET output is valid for VCC down to 1V. The device offers excellent circuit reliability and low cost by eliminating external components and adjustments.

A system reset of MAX7705  is provided during power-up, powerdown, and brownout conditions. When VCC is below the reset threshold, RESET is low and holds the P in reset. RESET will go high 280ms after VCC rises above the reset  hreshold. The MAX7705 is available in 8-pin DIP and SO packages.
