The STM705/706/707/708/813L 5V Supervisor is a 5V voltage supervisor produced by STMicroelectronics. It has low supply current, high-precision VCC monitoring, manual reset input and power-fail comparator.
The STM705/706/707/708/813L supervisors are self‑contained 5 V devices that monitor supply voltage and provide reset, watchdog and power‑fail functions for microprocessor systems. They are offered in 8‑pin SOIC and TSSOP packages and include precision voltage reference, comparator and optional watchdog timer.
The document provides detailed pin descriptions, electrical specifications, absolute maximum ratings, typical operating curves, package mechanical data and revision history, enabling designers to integrate the supervisors into hardware designs and to verify performance across temperature and load conditions.
