Product Summary

The TPS3705-50DRG4 is a processor supervisory circuit with power-fail. It provides circuit initialization and timing supervision, primarily for DSP and processor-based systems. The TPS3705-50DRG4 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, tt(out) = 1.6 s, WDO becomes active. The applications of the TPS3705-50DRG4 include: Designs Using DSPs, Microcontrollers or Microprocessors, Industrial Equipment, Programmable Controls, Automotive Systems, Portable/Battery Powered Equipment, Intelligent Instruments, Wireless Communication Systems, Notebook/Desktop Computers.
