Maxim MAX708SCSA

电源监控器2.93V1

Overview

The MAX706P/R/S/T, MAX706AP/AR/AS/AT, and MAX708R/S/T microprocessor (μP) supervisory circuits reduce the complexity and number of components required to monitor +3V power-supply levels in +3V to +5V μP systems. These devices significantly improve system reliability and accuracy compared to separate ICs or discrete components. The MAX706P/R/S/T and MAX706AP/AR/AS/AT supervisory circuits provide the following four functions:The only difference between the MAX706R/AR, MAX706S/AS, and MAX706T/AT is the reset-threshold voltage levels, which are 2.63V, 2.93V, and 3.08V, respectively. All have active-low reset output signals. The MAX706P/AP are identical to the MAX706R/AR, except the reset output signal is active-high. The watchdog timer function for the MAX706AP/AR/AS/AT disables when the WDI input is left open or connected to a high-impedance state of a low-leakage tri-state output. The MAX708R/S/T provide the same functions as the MAX706R/S/T and MAX706AR/AS/AT except they do not have a watchdog timer. Instead, they provide both active-low RESET and RESET outputs. As with the MAX706, devices with R, S, and T suffixes have reset thresholds of 2.63V, 2.93V, and 3.08V, respectively. These devices are available in 8-pin SO, DIP, and μMAX packages and are fully specified over the operating temperature range.
