STWD100 Watchdog Timer Circuits

STMicroelectronics STWD100 Watchdog Timer Circuits are self-contained devices which prevent system failures that are caused by certain types of hardware errors (non-responding peripherals, bus contention, etc.) or software errors (bad code jump, code stuck in loop, etc.). The STWD100 watchdog timer has an input, WDI, and an output, WDO. The input is used to clear the internal watchdog timer periodically within the specified timeout period, twd. While the system is operating correctly, it periodically toggles the watchdog input, WDI. If the system fails, the watchdog timer is not reset, a system alert is generated and the watchdog output, WDO, is asserted.

Standard Products

STMicroelectronics Standard Products are a broad range of industry-standard and drop-in replacements for the most popular general-purpose analog ICs, discretes, and serial EEPROMs. The Standard Products are manufactured to the highest quality standards with many AECQ-qualified for automotive applications. A comprehensive set of STMicroelectronics design aids, including SPICE, IBIS models, and simulation tools, is available to make adding to a design-in easy.
