Product Description
STMicroelectronics STWD100NYWY3F is a 5-pin watchdog timer integrated circuit housed in a compact SOT-23 surface mount package. It is engineered to enhance system reliability by monitoring operational status and preventing system failures caused by hardware or software errors. With a single internal timer and 5 pins, this watchdog timer ensures continuous supervision of embedded systems requiring precise timing.
The device supports a supply voltage range from 2.7V to 5.5V and can reliably operate within a wide temperature span from -40°C to 125°C, making it suitable for demanding industrial and automotive applications. Its small footprint, with dimensions of 2.9mm in length and 1.05mm in height, allows efficient use of PCB space.
When functioning normally, the watchdog output remains inactive. However, if the timer is not cleared within the predefined timeout, the watchdog output will assert a processor interrupt or system reset to restore normal operation. This feature protects against system lock-ups and ensures stability in mission-critical environments.
The STWD100NYWY3F series is ideal for industrial electronics, embedded control systems, automotive electronics, and other applications where robust timing and fault detection are essential. Its surface mount package type facilitates automated assembly and high-volume manufacturing.
Operates with minimum supply voltage of 2.7V and maximum supply voltage of 5.5V. Single internal timer with 5 pins for compact integration. Wide operating temperature range of -40°C to 125°C. Compact SOT-23 package measuring 2.9mm by 1.05mm.
Generates processor interrupt or reset if not cleared. Designed for industrial, automotive, and embedded system applications. Surface mount package for efficient PCB assembly.
This Watchdog Timer is an essential component for enhancing system stability and fault tolerance in electronics manufacturing and design. Available from EnvMart for engineering and industrial use.
