MIC2789 - Push-Button Reset

This page provides the datasheet information for the MIC2789, a member of the MIC2788 Push-Button Reset family.

Datasheet Summary

Description

The MIC2788/MIC2789 are low-current, ultra-small, pushbutton reset supervisors with long set-up delays.

The devices feature two manual reset inputs and two reset outputs.

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 microcontroll.

MIC2788/MIC2789 Push-Button Reset IC General Description The MIC2788/MIC2789 are low-current, ultra-small, pushbutton 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.
