Overview
The STM6822ZWY6F is a 5-pin supervisor IC manufactured by STMicroelectronics. It is part of the STM6xxx family, which provides microprocessor supervisory functions. This device includes a precision voltage reference and comparator to monitor the VCC input for out-of-tolerance conditions. When an invalid VCC condition occurs, the reset output (RST) is forced low or high, depending on the configuration. The STM6822ZWY6F also features a watchdog timer and a push-button reset input, making it a comprehensive solution for system supervision.
