General Description

The MAX6700/MAX6710 precision triple/quad voltage microprocessor (µP) supervisory circuits monitor up to four system-supply voltages and assert a single reset if any supply voltage drops below its preset threshold. These devices significantly reduce system size and component count while improving reliability compared to separate ICs or discrete components.

Features

♦ Monitor Up to Four Power-Supply Voltages

♦ Precision Factory-Set Reset Threshold Options for 5.0V, 3.3V, 3.0V, 2.5V, and 1.8V Supplies

♦ Adjustable Voltage Threshold Monitors Down to 0.62V with 1.5 Accuracy

♦ Low 35µA Supply Current

♦ Open-Drain RESET Output with 10µA Internal Pullup

♦ 5µs Propagation Delay (MAX6700)

♦ 140ms (min) Reset Timeout Period (MAX6710)

♦ RESET Valid to IN1 = 1V or IN2 = 1V

♦ Immune to Short Monitored Supply Transients

♦ Guaranteed from -40°C to +85°C

♦ Small 6-Pin SOT23 Package
