MAX14627, Low-Power Headset Detectors

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 compat

MAX14627 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 ope
