MAX708RESA-TG屬于集成電路（IC）的監(jiān)控器。由安森美半導(dǎo)體公司制造生產(chǎn)的MAX708RESA-TG監(jiān)控器PMIC 監(jiān)控器用于監(jiān)視和/或控制電路中的電壓軌，能夠連接微控制器以維持一定的功率限值。監(jiān)控器類型包括電池備用電路、監(jiān)控器、多電壓監(jiān)控器、電源監(jiān)控器、穩(wěn)壓器/監(jiān)控器、復(fù)位計時器、定序器、簡單復(fù)位/上電復(fù)位、智能開/關(guān)控制器、系統(tǒng)管理器、電壓檢測器和看門狗電路。

The MAX707/708 are cost?effective system supervisor circuits designed to monitor VCC in digital systems and provide a reset signal to the host processor when necessary. No external components are required.

The reset output is driven active within 20 sec of VCC falling through the reset voltage threshold. Reset is maintained with 200 mS of delay time after VCC rise above the reset threshold. The MAX707/708 have a low quiescent current of 12 μA at VCC = 3.3 V, an active?high RESET and active?low RESET with a push?pull output. The output is guaranteed valid down to VCC = 1.0 V. The MAX707/708 have a Manual Reset MR input and a +1.25 V threshold detector for power?fail input PFI. These devices are available in a Micro8 and SOIC?8 package.
