STM6823

5针主管与看门狗定时器和按钮复位 5-pin supervisor with watchdog timer and push-button reset

The STM6xxx supervisors are self-contained devices which provide microprocessor supervisory functions. 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 STM6322/6825 and/or a push-button MR reset input.

These devices are available in a standard 5-pin SOT23 package.
