Product Summary

The TPS3123J12DBVR is an ultralow voltage processor supervisory circuits provides circuit initialization and timing supervision, primarily for DSP and processor-based systems. During power-on, RESET is asserted when the supply voltage (VDD) becomes higher than 0.75 V. Thereafter, the supply voltage supervisor monitors VDD and keeps RESET output active as long as VDD remains below the threshold voltage (VIT). The applications of the TPS3123J12DBVR include Applications Using Low Voltage DSPs, Microcontrollers, or Microprocessors, Portable/Battery-Powered Equipment, Wireless Communication Systems, Programmable Controls, Industrial Equipment, Notebook/Desktop Computers, Intelligent Instruments.
