Description
Default Factory Setting
BQ24260 only: Shorting jumper for USB data lines DM (D-) and DP (D+). When
JP1
shorted, USB input current limit defaults to 1.5 A. Otherwise, USB100 mode is
SHORTED
selected.
JP2
Shorting jumper to connect DRV to anode of D1 STAT LED
SHORTED
JP3
Shorting jumper to connect DRV to anode of D1 INT LED
SHORTED
GATE = SYS: External PFET's gate tied to SYS and therefore disabled.
JP4
GATE = BGATE: External PFET's gate tied to BGATE pin and therefore controlled by
GATE = BGATE
IC.
CD = LO: Charge disable low for normal operation
JP5
CD = LO
CD = HI: Charge disable high to disable the buck converter and enter Hi-Z mode
TS = SIM(INT): Connects a potentiometer to the TS pin so that the potentiometer can
simulator a thermistor (that is, an internal, on-board thermistor). The potentiometer has
been preset per R5 and R6 so that the TS voltage is 0.5 x V (DRV).
JP6
TS = SIM(INT)
TS = EXT: Connects the TS pin to an external thermistor through J9. The resistor
divider formed by R5 and R6 has been sized to accommodate a 10-k
Ω
thermistor. If a
different thermistor is used, R5 and R6 must be resized.
bq24261 and bq24262 only
PSEL = LO: Input current limit is set to 1.5 A until changed by I2C.
JP7
PSEL = HI
PSEL = HI: For bq24261, input current limit is set to USB100 until changed by I2C. For
bq24262, input current limit is set to USB500 until changed by I2C.
