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 volt-
ages, and are fully compatible with Windows Mobile 7.
The devices need only three GPIOs from the host control-
ler 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. In standby mode,
microphone low-power pulsing is enabled to reduce sup-
ply 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. If a 3P headset without a microphone is
inserted, the low-power pulsing can be disabled by setting
the MODE input to high impedance.
The MAX14627 operates from a 2.5V to 5.5V input voltage
supply and 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.
