Product Introduction

Overview

The STM6824TWY6F is a 5-pin supervisor IC manufactured by STMicroelectronics, designed to provide comprehensive 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. Additionally, the STM6824TWY6F features a watchdog timer and a push-button reset input, enhancing system reliability and control.
