Wired Remote Controllers

/MAX1042

General Description

Features

The MAX11041/MAX11042 wired remote controllers

convert up to six or 30 different pushbuttons into an I²C

and 1% resistors, the MAX11041/MAX11042 are total

solutions over a single-wire interface. A wired remote

controller easily piggybacks to a standard 3.5mm

headphone jack using a fourth contact or one of the

audio signals.

♦ Detect Up to Six (MAX11042) or 30 (MAX11041)

Different Keys and Jack Insertion/Removal

♦ Work with Either 32Ω or 16Ω Headphones

♦ Add Remote-Control Functionality to Devices

Using a Simple Resistor and Switch Array

♦ Low-Power Operation Consuming a Supply

Current of Only 5µA (typ)

To conserve battery life, the MAX11041/MAX11042

consume only 5µA (typ) while reading keypresses in

real time without microprocessor (µP) polling. The

devices send the debounced keypress along with key

duration to the application processor over the I²C inter-

face. An 8-word FIFO buffer records up to four key-

press events to allow plenty of time for the application

processor to respond to the MAX11041/MAX11042.

♦ Work with Standard 2.5mm or 3.5mm 4-Pin

Headphone Jacks

♦ Support Hold Function to Lockout Keys

♦ 100kHz/400kHz I²C Interface

♦ Single 1.6V to 3.6V Supply Voltage Range

♦

15kV ESD Protection (IEC 61000-4-2)

The MAX11041/MAX11042 include 15kꢀ ꢁES protec-

tion devices on the FORCꢁ and EꢁNEꢁ inputs to ensure

IꢁC 61000-4-2 compliance without any external

ꢁES devices.
