SEMICONDUCTOR TECHNICAL DATA

The MC33884 Switch Monitor Interface is a monolithic silicon

integrated circuit (IC) that performs switch monitoring functions.

The device provides efficient interface between electrical switches

and low voltage microprocessors. The MC33884 supplies switch

contact pull–up and pull–down current while monitoring the input

voltage level. All inputs are protected for transients when

implemented with an appropriate static discharge capacitor used

on the inputs.

SCALE 1:1

There are four modes of operation – Sleep, Normal, Polling, and

Polling + INT Timer. Sleep mode reduces the current drain to a

quiescent current level of 10 A and disables the IC. Normal mode

interrupts the microprocessor whenever any external switch

changes it’s OPEN or CLOSED state. Polling mode reads a switch

status periodically and interrupts the microprocessor only when an

external switch is sensed as being CLOSED. The Polling + INT

Timer mode is similar to the Polling mode, with the addition of an

interrupt being sent to the microprocessor if a switch is sensed

CLOSED or upon the internal interrupt timer ”timing out”. An

interrupt is always ultimately sent to the microprocessor in this

mode. All modes of operation are easily programmed via the Serial

Peripheral Interface (SPI) control.
