Product Summary
The TPS3824-30DBVR supervisor provides circuit initialization and timing supervision, primarily for DSP and processor-based systems.The TPS3824-30DBVR device incorporates a manual reset input, MR. A low level at MR causes RESET to become active. The TTPS3824-30DBVR device includes a high-level output RESET. TPS3824-30DBVR has a watchdog timer that is periodically triggered by a positive or negative transition at WDI. When the supervising system fails to retrigger the watchdog circuit within the time-out interval, ttout, RESET becomes active for the time period td. This event also reinitializes the watchdog timer. Leaving WDI unconnected disables the watchdog.
