MAX14628 - Low-Power Headset Detectors

Download the MAX14628 datasheet PDF. This datasheet also covers the MAX14627 variant, as both devices belong to the same low-power headset detectors family and are provided as variant models within a single manufacturer datasheet.

General Description

The MAX14627/MAX14628 provide a simple solution for detecting the insertion and managing the operation of a 3.5mm stereo headset with a microphone.

Key Features

  • an internal 2.2V LDO output, while the MAX14628 operates from a 3.1V to 5.5V voltage supply and features an internal 2.8V LDO output voltage. Both devices control jack insertion detection by monitoring a 3.5mm socket with a normally open jack insertion switch. Additionally, the MAX14628 features open microphone detection. The MAX14627/MAX14628 are available in an 8-pin TDFN package, and are fully specified over the -40NC to +85NC extended temperature range. Benefits and Features S Versatile Ja.

19-6310; Rev 0; 5/12 EVALUATION KIT AVAILABLE MAX14627/MAX14628 Low-Power Headset Detectors with SEND/END Button Support General Description The MAX14627/MAX14628 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 needed to detect SEND/END button press events and generate required microphone bias voltages, and are fully compatible with Windows Mobile 7. The devices need only three GPIOs from the host controller to select between call mode and standby mode, and monitor the SEND/END and jack insertion status. In call mode, the low-noise LDO is enabled to provide DC bias to the externally preamplified microphone.
