STM1811MWX7F Description

Short technical summary and product information.

The STM1811MWX7F is a voltage supervisor IC from STMicroelectronics designed for monitoring a single voltage supply. It features a fixed threshold voltage of 4.37V with tight overvoltage and undervoltage thresholds of 4.49V and 4.25V respectively. The device operates from a supply voltage range of 1.2V to 5.5V, drawing a typical supply current of 16µA. A reset timeout of 100ms (minimum) ensures proper system initialization after power-up or voltage recovery. The output is active-low open-drain, capable of directly driving reset inputs of microcontrollers and other logic devices. The IC is available in a compact SOT-23-3 surface-mount package, measuring 3.04mm x 1.4mm with a height of 1.02mm. It is rated for operating temperatures from -40°C to +105°C, making it suitable for industrial and automotive environments. The STM1811MWX7F is part of the STM1811 series and is supplied on tape and reel with a factory pack quantity of 3000 units. This supervisor does not include manual reset, watchdog, battery backup, power fail detection, or chip enable functions, offering a simple and cost-effective solution for basic voltage monitoring.
