MAX802MEPA+

Supervisors Overview

The MAX802MEPA+ is a microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.2 V to 5.5 V and features a threshold voltage of 4.4 V with an overvoltage threshold of 4.5 V. The device provides a reset delay time of 280 ms and draws a typical operating supply current of 500 uA. It includes a watchdog timer and battery backup switch functionality, while power-fail detection is supported. The output type is active low push-pull, and it lacks manual reset and chip enable signals. The component is housed in an 8-PDIP package and supports through-hole mounting, functioning across a temperature range of -40°C to +85°C.

Supervisors Feature Summary
