Test Summary
2.2
Recommended Equipment for Testing
2.2.1
Power Supplies
Power Supply #1 (PS#1): a power supply capable of supplying 20 V at 1 A
2.2.2
Loads
A 20-V (or above), 1-A (or above) electronic load that can operate at constant current and constant
voltage mode or equivalent
2.2.3
Meters
Four Fluke 75 multimeters, (equivalent or better) or two equivalent voltage meters and two equivalent
current meters. The current meters must be capable of measuring 1 A + current.
2.3
Recommended Test Equipment Setup
1. Set the power supply #1 (PS#1) for 6.5 V ± 200 mVDC, 1-A ± 0.1-A current limit, and then turn off
supply.
2. Connect the output of PS#1 in series with a current meter (multimeter) to J1 (VBUS, GND).
3. Connect a voltage meter across J1 (VBUS, GND).
4. Connect Load #1 in series with a current meter to J2 (VBAT, GND). Turn off Load #1.
5. Connect a voltage meter across J2 (VBAT, GND).
6. Check all jumper shunts. JP1: OFF; JP2: OFF; JP3: OFF; JP4: OFF; JP5: connect 1-2 (External TS);
JP6: connect 2-3 (VBUS); JP7: connect 1-2 (charger OFF/ MODE high).
