MIC2789

EOL

Status: End of Life

Features:

  • 1.6V to 5.5V operating voltage
  • 2.9µA supply current when /MR0, /MR1 are not asserted
  • Asserting /MR0 and /MR1 for longer than set-up delay asserts reset output for the reset timeout period
  • Programmable delay (PDY) input selects 2.0s, 4.0s, or 6.0s set-up delay
  • Factory-programmed 140ms (min.) or 240ms (min.) reset timeout period
  • Integrated /MR0, /MR1 pull-up resistors (MIC2788)
  • Dual reset outputs:
  • Open-drain active-low reset (/RST) output
  • Push-pull active-high reset (RSTP) output
  • -40°C to +85°C ambient operating temperature range
  • 8-pin 2mm x 2mm x 0.55mm Thin MLF® package

Device Overview

Summary

The MIC2788/MIC2789 are low-current, ultra-small, push-button reset supervisors with long set-up delays. The devices feature two manual reset inputs and two reset outputs. The devices initiate a reset for the reset timeout period when the /MR0 and /MR1 inputs are asserted low for a period longer than the set-up delay. The two manual reset inputs and long set-up period help to avoid unintended system resets. Both manual reset inputs can be tied together if a single push-button reset is desired. The MIC2788 features integrated pull-up resistors on the /MR0 and /MR1 inputs, while the MIC2789 requires external pull-up resistors. The PDY input pin selects between a 2s, 4s, or 6s set-up period. Factory-programmed reset timeout periods of 140ms (min.) and 240ms (min.) are available. An active-low, open-drain reset output (/RST) and an active-high, push-pull reset output (RSTP) provide flexibility when interfacing to various microcontrollers, PMICs, or load switches. The MIC2788/MIC2789 consume a quiescent current of only 2.9µA and are offered in a tiny, space-saving 8-pin thin MLF® (2mm x 2mm x 0.55mm) package.
