Description
R1
24 k
AC mode fast-charge current resistor. Used to set the charging current in AC mode.
R2
24 k
USB mode fast-charge current resistor. Used to set the charging current in USB
mode.
R3
3.3 k
End of Charge current resistor. Used to set the termination current and, as
a “gas gauge” when measuring the voltage across on it.
R4
1 k
Pull up resistor. Connected between VREF and TH pin.
R5
1 k
Pull up resistor. To be used when the ST1 is connected with a LED.
R6
1 k
Pull up resistor. To be used when the ST2 is connected with a LED.
RT1
470
If a NTC is not used, a half value of R4 must be mounted to keep the TH voltage in
the correct window.
C1
1
F
Input capacitor.
C2
4.7
F Output capacitor.
C3
10 nF
TMAX capacitor. Used to set the maximum charging time.
C4
1 nF
VREF filter capacitor.
D1
GREEN ST1 LED.
D2
RED
ST2 LED.
J1
ST2 jumper. Using to select the LED or the external microcontroller.
J2
ST1 jumper. Using to select the LED or the external microcontroller.
J3
SD jumper. If open, the device is in SD mode; when closed, the device starts to
work.
J4
Low power/ high power USB mode selection jumper.
J5
AC/USB mode selection jumper.
