STWD100YNXWY3F Description

Short technical summary and product information.

The STMicroelectronics STWD100YNXWY3F is a supervisor integrated circuit designed for monitoring system power and providing reset functions. This device features a single voltage monitoring channel and a watchdog timer with a minimum timeout of 71ms. The reset signal is active low, and the output can be configured as open drain or open collector.

 

Designed for surface mounting, the STWD100YNXWY3F comes in a compact SOT-23-5 package, also referred to as SC-74A or SOT-753. It operates within a temperature range of -40°C to 125°C, making it suitable for various industrial and commercial applications. The component is specified with RoHS3 compliance and MSL 1 moisture sensitivity level.

 

This supervisor IC is ideal for applications requiring reliable system monitoring and reset capabilities to prevent system failures due to power fluctuations or software hangs. Its small footprint and operating temperature range allow for integration into space-constrained designs.
