5:1 Micro USB Switch
with Accessory detection and OVP
Overview
The LC824206XA is the IC suitable for use in multi function and high performance switch as well as compatible
accessory detector which supports micro USB connector for DSC, DVC and mobile phone.
This IC includes low impedance USB supply switch (100 mΩ) which enables high speed battery charge as well as
USB2.0-capable switch with low input capacitance, negative input-capable low distortion audio switch, UART,
microphone (Mono, Stereo), and various video signal switches, in addition MHL (Mobile High definition Link) switch
is integrated.
Also, this IC integrates auto detector for accessories which is capable of detecting accessories compliant to CEA936-A
automotive kit, ACA standard and Battery Charging Specification (BCS) rev.1.2 which includes MCPC standard
established in June 2010. In addition, it’s capable of detecting a lot of charger accessories, such as Dedicated (D+/Dshort) charger, Apple charger, SONY charger, CDP (Charging Downstream Port) charger, USB charger and so on.
Switching operation is controlled via I2C serial interface.

Function Description
Charger Detection
By using charger detector circuit including built-in D+/D- short-circuit detector, you can judge the connection of DP pin
and DM pin and then detect charger according to USB Charger and Battery Charging Specification Revision 1.2 as well as
CEA936-A automotive kit specification. This IC can detect the charger of the following list.
Detectable charger list
Standard Downstream Port (USB mode)
Dedicated Charging Port (D+/D- short ACC)
Charging Downstream Port (USB mode)
Apple Charger
SONY Charger
D- High Charger (Basic CarKit Type1,2 ACC)
VBUS only ACC (No Charger Detect)
Accessory ID Detection
Accessory is detected according to CEA936-A automotive kit and ACA standard including MCPC standard using ID
detection circuit including built-in 5-bit ADC. Accessories are judged from the resistance value of accessory (RID)
connected to ID pin. ID range of RID varies depends on each standard. See Resistance (RID) and Detectable accessory for
the further details.
