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 micro-
phone 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. In call mode, the low-noise LDO is enabled to
provide DC bias to the externally preamplified micro-
phone. In standby mode, microphone low-power pulsing
is enabled to reduce supply current while waiting for a
SEND/END button press event. Two open-drain outputs
signal the host controller when an insertion/removal or
SEND/END button press event occurs.
The MAX14579E/MAX14579AE manage jack insertion
detection by monitoring a 3.5mm socket with a normally
open jack insertion switch.
The devices are available in an 8-pin TDFN package,
and are fully specified over the -40NC to +85NC extended
temperature range.
