LC824204-13YB

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 1.1 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)

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.
