STM818 系列 4.65 Vrst 140 ms 5 V 监控器 带电池切换功能 - SOIC-8
The STM690A/692A/703/704/802/805/817/818/819 supervisors are self-contained devices which provide microprocessor supervisory functions with the ability to non-volatize and write-protect external LPSRAM. A precision voltage reference and comparator monitors the VCCinput for an out-of-tolerance condition. When an invalid VCCcondition occurs, the reset output RST is forced low or high in the case of RST. These devices also offer a watchdog timer except for STM703/704/819 as well as a power-fail comparator except for STM818 to provide the system with an early warning of impending power failure.
These devices are available in a standard 8-pin SOIC package or a space-saving 8-pin TSSOP package.
