MAX708集成电路（IC）的监控器规格书PDF中文资料

MAX708属于集成电路（IC）的监控器。由安森美半导体制造生产的MAX708监控器PMIC 监控器用于监视和/或控制电路中的电压轨，能够连接微控制器以维持一定的功率限值。监控器类型包括电池备用电路、监控器、多电压监控器、电源监控器、稳压器/监控器、复位计时器、定序器、简单复位/上电复位、智能开/关控制器、系统管理器、电压检测器和看门狗电路。

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.
