STM811MW16F Description

Short technical summary and product information.

The STM811MW16F is a power management integrated circuit from STMicroelectronics, specifically functioning as a supervisor. It monitors a single voltage level and provides an active-low reset output. The device operates within a supply voltage range of 1V to 5.5V, with a nominal threshold voltage of 4.38V. The reset threshold is precisely controlled between 4.31V and 4.45V, ensuring reliable system resets.

 

This supervisor IC features a reset timeout of 140ms and an operating supply current of typically 15uA, making it suitable for low-power applications. The output stage is push-pull, totem pole.

 

Packaged in a compact SOT-143-4 surface-mount case, the STM811MW16F is designed for easy integration into printed circuit boards. It operates across a wide temperature range of -40°C to 85°C. The component is RoHS3 compliant and has an MSL rating of 1.
