Jumper Description Default Factory Setting
1-2 (TS = INT): Connects a potentiometer to the TS so that the potentiometer can
emulate a thermistor. The potentiometer has been preset to approximately 3.4 kΩ so
that the TS voltage is 0.5 x V (DRV).
JP1 1-2 (TS = INT)
2-3 (TS = EXT): Connects the TS pin to an external thermistor. The resistor divider
formed by R1 and R3 has been sized to accommodate a 10-kΩ thermistor. If a different
thermistor is used, R1 and R3 must be resized.
1-2 (FET GATE = SYS): External PFET's gate tied to SYS and therefore disabled.
JP2 2-3 (FET GATE = BGATE): External PFET's gate tied to BGATE pin and therefore 2-3 (FET GATE = BGATE)
controlled by IC.
Shorting jumper for USB data lines DM (D-) and DP (D+). When shorted, USB input
JP3 SHORTED
current limit defaults to 1.5 A. Otherwise, USB100 mode is selected.
bq24161 and bq24168 only
1-2 (PSEL = LO): Indicates that an ac adapter is connected to the USB input and sets
JP4 the USB input current limit to 1.5 A. 2-3 (PSEL = HI)
2-3 (PSEL = HI): Indicates that a USB source is connected to the USB input and sets
the input current limit to 500 mA.
1-2 (CD = LO): Charge disable low for normal operation
JP5 1-2 (CD = LO)
2-3 (CD = HI): Charge disable high to disable charge and enter Hi-Z mode

2 Test Summary
This procedure describes one test configuration of the HPA721 evaluation board for bench evaluation.
2.1 Definitions
The following naming conventions are followed.
VXXX : External voltage supply name (VADP, VBT, VSBT)
LOADW: External load name (LOADR, LOADI)
V(TPyyy): Voltage at internal test point TPyyy. For example, V(TP12) means the voltage at
TP12.
V(Jxx): Voltage at header Jxx
V(TP(XXX)): Voltage at test point XXX. For example, V(ACDET) means the voltage at the test
point which is marked as ACDET.
