www.ti.com Test Summary
Or: Four equivalent voltage meters and three equivalent current meters.
The current meters must be capable of measuring 5A+ current.
2.6 Equipment Setup
• Set the power supply #1 (PS#1) for 16V ± 200mV, 2A ± 0.1A current limit and then turn off supply.
• Connect the output of PS#1 in series with a current meter (multi-meter) to J1 (VIN, GND).
• Connect a voltage meter across J1 (VIN, PGND).
• Connect Load #1 in series with a current meter to J2 (VBAT, PGND). Turn off Load #1.
• Connect a voltage meter across J2 (VBAT, PGND).
• Check all jumper shunts. JP1: connect 1-2 (External TS); JP2: ON; JP3: connect 1-2 (3-cell); JP4: ON;
JP5: OPEN.

2.7 Procedure
Make sure EQUIPMENT SETUP steps are followed.
1. Disconnect LOAD #1. Turn on PS#1
Measure → V(J2(VBAT)) = 0.5V ± 500mV
Measure → V(TP(VREF)) = 3.3V ± 200mV
Measure → V(TP(REGN)) = 0.5V ± 500mV
2. Charger Enable
Connect 2-3 of JP1 (Internal TS); Short JP4 (Charger Enable)
Measure → V(TP(VREF)) = 3.3V ± 200mV
Measure → V(TP(REGN)) = 6V ± 200mV
Measure → V(J2(VBAT))=12.6V ± 200mV
3. Charge Voltage Setting
Connect 2-3 of JP3
Measure → V(J2(VBAT))=4.2V ± 200mV
Disconnect JP3
Measure → V(J2(VBAT))=8.4V ± 200mV
4. Charge Current Regulation and Battery Temperature Qualification
Reconnect 1-2 of JP3
Reconnect LOAD#1. Turn on. Use the constant voltage mode. Set the output voltage to be 10V.
Measure → I(J2(VBAT)) = 0.2A ± 100mA
