MAXIM MAX11041 Wired Remote Controller 数据手册

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).
