MAX14579AE Datasheet Low-power Headset Detectors

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: MAX14579E/MAX14579AE 19-5964; Rev 0; 06/11 EVAALVUAAILTAIOBNLEKIT Low-Power Headset Detectors with SEND/END Button Support.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The MAX14579E/MAX14579AE provide a simple solution for detecting the insertion and managing the operation of a 3.5mm stereo headset with a microphone.

These devices integrate all circuitry required to detect SEND/ END button press events and generate required microphone bias voltages.

The devices are managed with only three GPIOs from the host controller to select between call mode and standby mode, and monitor the SEND/END and jack insertion status.
