7 / 14 page LC824204-13YB No.A2221-7/14 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. 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.
