STM809SWX6F Description

Short technical summary and product information.

The STMicroelectronics STM809SWX6F is a voltage supervisory circuit housed in a compact SOT-23-3 package. This component is designed to monitor a single voltage supply, ensuring system stability during power fluctuations. It provides an active-low, push-pull output and features a reset threshold of 2.93V with a minimum delay time of 140ms.

 

With a maximum supply voltage of 5.5V and an operating temperature range of -40°C to +85°C, the STM809SWX6F is suitable for a variety of applications. Its low operating supply current of 15µA and maximum power dissipation of 320mW make it an efficient choice for power-sensitive designs. The device is surface-mount compatible and supplied on a reel.

 

Key specifications include multiple threshold voltage options (3V, 3.3V, 5V), an overvoltage threshold of 2.96V, and an undervoltage threshold of 2.89V. The STM809SWX6F is a reliable solution for power-on reset and brown-out detection in embedded systems.
