STM810集成电路（IC）的监控器规格书PDF中文资料

STM810属于集成电路（IC）的监控器。由意法半导体集团制造生产的STM810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。

SUMMARY DESCRIPTION

The STM809/810/811/812 MICROPROCESSOR RESET Circuits are low-power supervisory devices used to monitor power supplies. They perform a single function: asserting a reset signal whenever the VCCsupply voltage drops below a preset value and keeping it asserted until VCChas risen above the preset threshold for a minimum period of time (trec). The STM811/812 also provide a push-button reset input (MR).
