Wired Remote Controller
General Description
The MAX11041 wired remote controller converts up to
30 different pushbuttons into an I2C register. Together
with low-cost pushbutton switches and 1% resistors,
the MAX11041 is a total solution 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.
To conserve battery life, the MAX11041 consumes only
5µA (typ) while reading keypresses in real time without
microprocessor (µP) polling. The device sends the
debounced keypress along with key duration to the
application processor over the I2C interface. An 8-word
FIFO buffer records up to four keypress events to allow
plenty of time for the application processor to respond
to the MAX11041.
The MAX11041 includes ±15kV ESD protection devices
on the FORCE and SENSE inputs to ensure IEC 61000-4-2
compliance without any external ESD devices.
The MAX11041 is available in a 12-pin TQFN package.
The device is specified over the extended temperature
range (-40°C to +85°C).

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
