SW6121-Supports multi-protocol two-way fast charging mobile power supply solution such as QC

Chip Solution Battery Power Management Chip SW6121

The solution supports 1 standard TYPEA and 1 TYPEC (layout limited) socket as output, both of which support QC3.0/QC2.0/FCP/PE2.0/PE1.1/SFCP fast charging output. (TYPEC has no input function and cannot be used for charging)

Supports TYPEA and TYPEC to discharge to the outside at the same time. At this time, the output voltage is 5V.

1 TYPEB interface charging input, supports high voltage input. The charging current is set according to the fast charge input voltage. When the input voltage is normal 5V, the charging current is set to 2.5A; when the input voltage is fast charging, the charging current is set to 4A.

Supports 5 LED light power indicators and 1 fast charging LED indicator light.

The battery type can be set through BSET/HLEDPin.

(Default floating 4.2V)

When floating, set the 4.2V battery;

When connecting a 62KΩ resistor to ground, set a 4.35V battery;

When connecting a 30KΩ resistor to ground, set a 4.4V battery;

When connecting a 10KΩ resistor to ground, set a 4.3V battery.

Button function: short press to turn on the power to display the battery level, double press to turn off the boost output, and long press to turn on and off the backlight.

Note: When connecting the battery for the first time, it needs to be charged and activated.
