Table 2. Jumper Connections
Jack Description Factory Setting
JP1 TS1 to TS2 connection Shunt installed
JP2 D- 20k pull down Shunt not installed
JP3 VSYS pull-up for STAT, CE, INT Shunt installed
JP4 USB current limit selection pin during buck mode and PSEL is high (JP1-High); Shunt not installed
enable pin during boost mode.
In buck mode: OTG = High, I
IN
limit = 500 mA;
OTG = Low, I
IN
limit = 100 mA.
The boost mode is activated when the REG01[5:4] = 10 and OTG pin is HIGH.
JP5 /CE pin setting: Pull low to enable the charge Shunt not installed
(GUI also can pull CE low)
JP6 200- Ω short between D+ and D- Shunt not installed
JP7 TS2 resistor divider pull-up source (REGN) connection Shunt installed
JP8 Internal 10k to ground to TS2 Shunt installed
JP9 D+ 20k Pull down Shunt not installed

2 Test Summary
Section 2.1 – Section 2.3 explain the equipment, the equipment setup, and the test procedures.
2.1 Equipment
2.1.1 Power Supplies
Power supply #1 (PS#1): a power supply capable of supplying 5 V at 1 A is required. While this part can
handle larger voltage and current, it is not necessary for this procedure.
2.1.2 Load #1 (4-Quadrant Supply, Constant Voltage < 4.5 V)
A 0–20 V/0–5 A, > 30-W system, DC electronic load and setting as constant voltage load mode.
Or:
Kepco load: BOP 20–5M, DC 0 to ±20 V, 0 to ±5 A (or higher)
Or:
Real single-cell battery
2.1.3 Load #2 – Use with Boost Mode
PMID-to-GND load, 10 Ω , 5 W or greater
