STM1811MWX7F ST Supervisor IC | SOT-23-3 | 2.63V Threshold, Active Low

Product Overview

The STM1811MWX7F is a microprocessor supervisory circuit manufactured by STMicroelectronics. It monitors the power supply voltage in digital systems and provides a reset signal to the microprocessor during power-up, power-down, and brown-out conditions. The device is available in a compact SOT-23-3 package, making it suitable for space-constrained applications. It features a fixed reset threshold voltage of 2.63V and an active-low, open-drain reset output. The reset output remains asserted for a minimum of 140ms after VCC rises above the reset threshold, ensuring proper system initialization.
