家庭的pt7m7xxx微处理器（μP）监督
电路的目标是提高可靠性和准确性。
在电源系统中的电源电路。这些设备
减少组件的复杂性和数量
需要监控电源和电池功能。
主要功能是：
主张复位输出时，上电，断电
和μP系统掉电条件；
检测电源故障或低电池条件
1.25V的门槛检测器；
看门狗功能；

手动复位。

The PT7M7xxx family microprocessor (μP) supervisory
circuits are targeted to improve reliability and accuracy
of power-supply circuitry in μP systems. These devices
reduce the complexity and number of components
required to monitor power-supply and battery functions.
The main functions are:
Asserting reset output during power-up, power-down
and brownout conditions for μP system;
Detecting power failure or low-battery conditions with
1.25V threshold detector;
Watchdog functions;
Manual reset.
