Introduction
1.6 Control and Key Parameters Setting
Jumper Description Default Factory Setting
JP1 Leave jumper open OPEN
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: Connects a potentiometer to the TS pin so that the potentiometer can
simulator a thermistor. The potentiometer has been preset per R5 and R6 so that the
TS voltage is 0.5 x V (DRV).
JP6 TS=SIM
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.
PSEL = LO: Input current limit is set to 1.5 A until changed by I2C.
JP7 PSEL = HI
PSEL = HI: Input current limit is set to USB100 until changed by I2C.
