1.6 Control and Key Parameters Setting
Jumper Description Default Factory Setting
JP1 N/A Not installed
JP2 Shorting jumper to connect DRV to annode of D1 STAT LED SHORTED
JP3 Shorting jumper to connect DRV to annode of D1 INT LED SHORTED
CD = LO: Charge disable low for normal operation
JP4 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 is preset per R5 and R6 so that the TS
voltage is 0.5 x V (DRV).
JP5 TS=SIM
TS = EXT: Connects the TS pin to an external thermistor through J9. The resistor
divider formed by R5 and R6 is sized to accommodate a 10-k
Ω thermistor. If a different
thermistor is used, R5 and R6 must be resized.
PSEL = LOW: Input current limit is set to 1.5 A until changed by I2C.
JP6 PSEL = HIGH: Default mode input current limit is set to 100 mA until changed by I2C. PSEL = LOW
Default mode input current limit is set to 1.5 A until changed by I2C.
