TABLE 2. DESCRIPTION OF JUMPERS
JUMPER
DESCRIPTION
H1
The jumper installed to connect R3 and R4 to VBIAS pin as power supply to the LED1 and LED2
H2
The jumper installed to short ISET2 pin to ground
H3
The jumper to short ISET1 pin to ground
H4
If a shunt is inserted on H4, TIME pin is shorted to ground, and the TIMEOUT function will be disabled. If H4 is open, TIMEOUT function
will be enabled and timeout can be set with capacitor at the pin
H5
If a shunt is installed on H5, VBIAS will be scaled down to 2.5V at the RTH pin by the resistive divider of R12 and R13 and the charger
will operate in normal mode. If H5 is open, RTH pin will be pulled high, and the charger is in suspend mode
H6
It is a 3 pin jumper. If a shunt is inserted on the left two pins, the EN pin is connected to ground and the charger is enabled. If a shunt
is inserted on the right two pins, the EN pin is connected to VBIAS and the charger is disabled
JP8
Parallels an additional 50k
Ω
resistor to ISET1 pin such that the charge current will be set at 1.5A with JP9 open
JP9
Parallels an additional 100k
Ω
resistor to ISET1 pin such that the charge current will be set at 1A with JP8 open. If both JP8 and JP9
are inserted, the charge current will be 2A. If both JP8 and JP9 are open, the charge current will be 500mA
JP10
Parallels an additional 600k
Ω
resistor to ISET2 pin to set a trickle charge current of 140mA
