Power Supply Supervisor

Description

l The MAX809 series are highly accurate, low power consumption voltage detectors, manufactured using CMOS and laser trimming technologies. A delay circuit is built-in to each detectors. Detect voltage is extremely accurate with minimal temperature drift. Both CMOS and N-ch open drain output configurations are available. Since the delay circuit is built-in, peripherals are unnecessary and high density mounting is possible.

Features

l Low power consumption

l Low temperature coefficient

l Built-in delay circuit: 200ms

l High input voltage (up to 8V)

l Output voltage accuracy: tolerance ±2%

l SOT23 package 

Applications

l Microprocessor reset circuitry

l Memory battery back-up circuits

l Power on reset circuits

l System battery life and charge voltage monitors

l Delay circuitry
