ADM709集成电路（IC）的监控器规格书PDF中文资料

ADM709属于集成电路（IC）的监控器。由亚德诺半导体技术有限公司制造生产的ADM709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。

GENERAL DESCRIPTION

The ADM709 contains a power supply monitor which generates a system reset during power-up, power-down and brownout conditions. When VCC falls below the reset threshold, RESET goes low and holds the µP in reset. On power-up the RESET output is held low for 140 ms after VCC rises above the thresh old. The RESET output remains operational with VCC as low as 1 V.

Three supply-voltage threshold levels are available suitable for +5 V, +3.3 V and for +3 V supply monitoring. The actual reset voltage threshold is given below.

The ADM709 is available in 8-pin DIP and SOIC packages.
