STM812MW16F ST Microprocessor Supervisor | SOT-143-4 | 3.08V Threshold, Active Low Reset

Product Overview

The STM812MW16F is a microprocessor supervisory circuit manufactured by STMicroelectronics, designed to monitor power supplies in digital systems. It provides a reset output during power-up, power-down, and brown-out conditions. The device ensures that the system microcontroller (MCU) or processor starts up in a known state, preventing code execution errors. With a fixed threshold voltage of 3.08V, it is ideal for 3.3V and 3.0V powered systems. The SOT-143-4 package offers a compact footprint for space-constrained applications.
