STM811MW16F ST Microprocessor Supervisor | SOT-143-4 | 1.6V Threshold, Active Low Reset

Product Overview

The STM811MW16F 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 microprocessor (MPU) is properly reset during unstable power conditions. Housed in a compact SOT-143-4 package, it is ideal for space-constrained applications.
