Product Summary

The TPS3838K33QDBVRQ1 is a nanopower supervisory circuit. It 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 1.1 V. Thereafter, the TPS3838K33QDBVRQ1 monitors VDD and keeps RESET output active as long as VDD remains below the threshold voltage VIT. The applications of the TPS3838K33QDBVRQ1 include Applications Using Low-Power DSPs, Microcontrollers, or Microprocessors, Portable/Battery-Powered Equipment, Intelligent Instruments, Wireless Communication Systems, Notebook Computers Automotive Systems.
