supports QC3.0 / QC2.0 / AFC / FCP / SCP / PE2.0 / PE1.1 / SFCP fast charge output. Type-C port

supports PPS / PD3.0 / PD2.0 / QC4+ / QC3.0 / QC2.0 / AFC / FCP / SCP / PE2.0 / PE1.1 / SFCP fast

charge output, and PD3.0 / PD2.0 / AFC / FCP / SCP / PE1.1 fast charge input. Micro-B supports

AFC/FCP/SCP/PE1.1 fast charge input. Lightning supports PD3.0/PD2.0 fast charge input, and

Lightning cable decryption.

When short key occurs or load inserts, Type-A1/Type-A2 port will turn on to power supply extern

device, and light load detection will turn off Type-A1/Type-A2/Type-C port. Light load current is

related to power path MOS. if power path MOS Rdson is 10mΩ, the light load current will be about

60mA/40mA when output voltage is 5V/high voltage. When SOURCE is attached, Type-C port will

turn on and charger will automatically turn on to charge battery. When SINK is attached, Type-C port

will turn on and boost will automatically turn on to supply device. When SINK is unattached, Type-C

port will turn off and boost will automatically turn off. Type-C port also support light load detection.

When SINK is light load, Type-C port and boost will turn off to reduce power consumption.When

adapter inserts, Micro-B or Lightning port will turn on and charger will automatically turn on.

The SW6206 supports charging the battery and supplying extern device simultaneously, and this

function can be disabled if not needing. When only one port turns on, it supports fast charge input and

output. When two or three ports turn on, it only supports 5V input and output. In this situation, charger

hold voltage is set to 4.8V. if input voltage drops due to the weak power supply of adapter, charge

current will automatically fall down so the input voltage holds to 4.8V and supplies extern device in

priority.

The SW6206 supports Type-A1/Type-A2/Type-C ports supplying extern devices simultaneously and

only supports 5V output.

9.4. Mode Set

The SW6206 supports wireless charge, small current charge and flash light driver modes. These three

modes are set by register in I2C mode, and set by pin in led mode.

The SW6206 supports wireless charge mode. In wireless charge mode, wireless charge module is

connected to Type-A2 port. Light load threshold of Type-A2 port is set to 240mA/115mA in 5V/high

voltage output, and light load detect time is set to 32S. Wireless charge mode is set when LED1/SCK

pin connects a 100KΩ resister to ground.

The SW6206 supports small current charge mode, and can charge small current device such as

bluetooth headset. When enter into small current charge mode, light load detect will be disabled for

two hours, and double short key will also quit this mode. Besides, fuel gauge display will also change

to indicate it is in small current charge mode. Small current charge mode is set when LED2/SDA pin

connects a 100KΩ resister to ground.

The SW6206 supports flash light driver mode also called WLED mode. CCL/WLED Pin can be

configured to WLED driver or PD fast input function of Lightning port, only one of these two functions

can be used in one application. When LED3/IRQ pin connects a 100K Ω resister to ground,
