STM705, STM706 STM707, STM708, STM813L 5 V supervisor is a voltage monitor chip produced by ST company. Its features are wide voltage range, working voltage is 5V, and it still ensures RST output when the voltage drops to 1.0V. It is suitable for industrial grade applications.
This document provides the specifications and features for the STM705, STM706, STM707, STM708, and STM813L 5 V supervisor devices. These self-contained devices provide microprocessor supervisory functions by monitoring the VCC input for out-of-tolerance conditions and forcing the reset output accordingly. They also offer a watchdog timer (except for STM707/708) and a power-fail comparator to provide early warning of impending power failure.
