6. JMP1: ON, JMP2: ON, JMP3: ON, JMP4: ON, JMP5: ON, JMP6: ON, JMP7: ON, JMP8: OFF
7. After the preceding steps, the test setup for HPA245 (bq2430x/1x/8x DSG EVM) is shown in Figure 2 .
Figure 2. Charger IC Test Setup for HPA245 (bq2430x/1x/8x DSG EVM)
1. Enable output of Load #2
2. Enable output of PS#1
3. Increase the voltage of PS #1 to 5 V ± 0.1 V.
Observe → D4 off, D5 off, D6 on.
4. Uninstall JMP7 (enable U2).
Measure → Ibat = 200 mA ± 20 mA (For HPA245-001, -002, -003, -004, -013 only).
Measure → Ibat = 700 mA ± 70 mA (For HPA245-005, -006, -007, -008, -009, -010, -011, -012 only).
Observe → D4 on, D5 off, D6 on.
5. Disable the output of Load #2.
6. Disable the output of PS#1 and remove PS #1 from J3
1. Connect the output of power supply #1 to J1 (DC+, DC–).
2. Connect a voltage meter across J1 (DC+, DC–).
3. JMP1: ON, JMP2: ON, JMP3: OFF, JMP4: ON, JMP5: ON, JMP6: ON, JMP7: OFF, JMP8: ON.
4. After the preceding steps, the test setup for HPA245 (bq2430x/1x/8x DSG EVM) is shown in Figure 3 .
