    TPS3803-01QDCKREP

    The TPS3803 and TPS3805 families of supervisory circuits
    provide circuit initialization and timing supervision, primarily
    for DSPs and processor-based systems.
    The TPS3803G15 device has a fixed-sense threshold voltage
    VIT set by an internal voltage divider, whereas the
    TPS3803−01 has an adjustable SENSE input that can be
    configured by two external resistors. In addition to the fixed
    sense threshold monitored at VDD, the TPS3805 devices
    provide a second adjustable SENSE input. RESET is
    asserted in case any of the two voltages drops below VIT.
    During power on, RESET is asserted when supply voltage
    VDD becomes higher than 0.8 V. Thereafter, the supervisory
    circuit monitors VDD (and/or SENSE) and keeps RESET
    active as long as VDD or SENSE remains below the threshold
    voltage VIT. As soon as VDD (SENSE) rises above the
    threshold voltage VIT, RESET is deasserted again. The
    product spectrum is designed for 1.5 V, 3.3 V, and adjustable
    supply voltages. The devices are available in a 5-pin SC-70
    package.

      (1) Component qualification in accordance with JEDEC and industry
      standards to ensure reliable operation over an extended
      temperature range. This includes, but is not limited to, Highly
      Accelerated Stress Test (HAST) or biased 85/85, temperature
      cycle, autoclave or unbiased HAST, electromigration, bond
      intermetallic life, and mold compound life. Such qualification
      testing should not be viewed as justifying use of this component
      beyond specified performance and environmental limits.
