IC Description
per Setting
1-2: FET GATE = BGATE: External PFET's gate tied to BGATE pin and therefore controlled
by IC.
1-2 (FET GATE =
All JP1 2-3: FET GATE = SYS: External PFET's gate tied to SYS and therefore disabled.
BGATE)
It is recommended that this jumper be changed only when the device is not enabled or in Hi-Z
mode so that the PFET's gate is never left open.
1-2: CE1 = HI: Active-low enable for reduced VBAT voltage (if CE2 = LO) or suspended
bq241 charging (if CE2 = HI)
JP2 2-3 (CE1 = LO)
65 2-3: CE1 = LO: Active-low enable for full current charging (if CE2 = LO) or charging at half
current (if CE2 = HI)
bq241
66 1-2: CE = HI: Active-low charge enable high to disable charge and enter Hi-Z mode
JP2 2-3 (CE = LO)
bq241 2-3: CE = LO: Active-low charge enable low for normal operation
67
1-2: IUSB3 = HI
2-3: IUSB3 = LO
All JP3 2-3 (IUSB3 = LO)
See data sheet Table 1 for description of USB input current limit and VINDPM threshold
setting. Default setting is for 500-mA input current limit and 4.68-V threshold.
1-2: IUSB2 = HI
2-3: IUSB2 = LO
All JP4 2-3 (IUSB2 = LO)
See data sheet Table 1 for description of USB input current limit and VINDPM threshold
setting. Default setting is for 500-mA input current limit and 4.68-V threshold.
1-2: IUSB1 = HI
2-3: IUSB1 = LO
All JP5 1-2 (IUSB1 = HI)
See data sheet Table 1 for description of USB input current limit and VINDPM threshold
setting. Default setting is for 500-mA input current limit and 4.68-V threshold.
1-2 (CE2 = HI): Active-low enable for charging at half current (if CE1 = LO) or suspended
bq241 charging (if CE1 = HI)
JP6 2-3 (CE2 = LO)
65 2-3 (CE2 = LO): Active-low enable for full current charging (if CE1 = LO) or reduced VBAT
voltage (if CE1 = HI)
1-2 (TS = EXT): Connects the TS pin to an external thermistor. The resistor divider formed by
bq241 R4 and R5 has been sized to accommodate a 10-kΩ thermistor. If a different thermistor is
66 used, R4 and R5 need to be resized.
JP6 2-3 (TS = INT)
bq241 2-3 (TS = INT): Connects a potentiometer to the TS pin so the potentiometer can emulate a
67 thermistor. The potentiometer has been preset to approximately 3.4 kΩ so that the TS voltage
is 0.5 x V(DRV).
