MAX709SEPA+ Description

Short technical summary and product information.

The MAX709SEPA+ is a power supply monitor with a reset output, designed by Analog Devices / Maxim Integrated. It ensures system integrity by generating a reset signal during power-up, power-down, and brownout events. This IC is suitable for +5V, +3.3V, and +3V powered systems, eliminating the need for external components.

 

A key feature is the guaranteed correct reset state even when VCC drops to 1V. The device provides a minimum 140ms power-on reset delay after VCC rises above the selected threshold. It is immune to short negative VCC transients, enhancing circuit reliability.

 

Available in an 8-pin DIP package, the MAX709SEPA+ is designed for low-cost processor systems where minimal component count is desired. It operates within a temperature range of 0°C to 70°C for the 'C' variants and -40°C to 85°C for the 'E' variants. The device offers precise power-down reset thresholds selectable via suffix, with options like 4.65V (L), 4.40V (M), 3.08V (T), 2.93V (S), and 2.63V (R).
