Power-Supply Monitor with Reset

_______________General Description

___________________________Features

♦ +5V, +3.3V, and +3V Versions

The MAX709 provides a system reset during power-up,

power-down, and brownout conditions. When V_CCfalls

below the reset threshold, RESET goes low and holds

the µP in reset for 140ms min after V_CCrises above the

threshold.

♦ No External Components

♦ Low Cost

♦ Precise Power-Down Reset Threshold

♦ 140ms Min Power-On Reset Delay

♦ Immune to Short Negative V_CCTransients

♦ 8-Pin DIP, µMAX, and SO Packages

The RESET output is guaranteed to be in the correct

state with V_CCdown to 1V. The MAX709 provides

excellent circuit reliability and low cost by eliminating

external components and adjustments when used with

+5V, +3.3V, or +3V powered systems. The MAX709 is

available 8-pin DIP, µMAX, and SO packages.

♦ Low Supply Current: 35µA - MAX709R/S/T

65µA - MAX709L/M
