MAX6703TKA-T

低电压， SOT23レP监控电路，带有电源失效输入/输出，手动复位及看门狗定时器 Low-Voltage, SOT23 レP Supervisors with Power- Fail In/Out, Manual Reset, and Watchdog Timer

General Description

The MAX6701–MAX6708 microprocessor µP supervisory circuits reduce the complexity and components required to monitor power-supply functions in µP systems. These devices significantly improve system reliability and accuracy compared to separate ICs or discrete components. The MAX6701–MAX6708 family provides four functions: a reset output during power-up, power-down, and brownout conditions; an independent watchdog output that goes low if the watchdog input has not been toggled within 1.6s; a 0.62V threshold detector for power-fail warning; and an active-low manual reset input.
