Product Summary

The TPS3801L30DCKR is a supervisory circuit monitor supplies voltages to provide circuit initialization and timing supervision, primarily for DSPs and other processor-based systems. The TPS3801L30DCKR asserts a push-pull RESET signal when the SENSE (adjustable version) or VDD (fixed version) drops below a preset threshold. The applications of the TPS3801L30DCKR include Applications Using DSPs, Microcontrollers, or Microprocessors, Wireless Communication Systems, Portable/Battery-Powered Equipment, Programmable Controls, Intelligent Instruments, Industrial Equipment, Notebook/Desktop Computers, Automotive Systems.
