General Description

The MAX803/MAX809/MAX810 are microprocessor (µP) supervisory circuits used to monitor the power supplies in µP and digital systems.

They provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with +5V, +3.3V, +3.0V, or +2.5V-powered circuits.

These circuits perform a single function: they assert a reset signal whenever the VCC supply voltage declines below a preset threshold, keeping it asserted for at least 140ms after VCC has risen above the reset threshold.

Key Features

o Precision Monitoring of +2.5V, +3V, +3.3V, and +5V Power-Supply Voltages o Fully Specified Over Temperature o Available in Three Output Configurations Open-Drain RESET Output (MAX803) Push-Pull RESET Output (MAX809) Push-Pull RESET Output (MAX810) o 140ms min Power-On Reset Pulse Width o 12µA Supply Current o Guaranteed Reset Valid to VCC = +1V o Power Supply Transient Immunity o No External Components o 3-Pin SC70 and SOT23 Packages MAX803L/M/R/S/T/Z, MAX809J/L/M/R/S/T/Z, MAX810L/M/R/S/T/Z.
