2.3.2.1
Software setup (all of
is done in the GUI):
1. Device address: bq24190/192/192i/193/196 (6B) and bq24292i
2. Click the Read button
3. Select Disabled for I
2
C Watchdog Timer Limit
4. Set Input Voltage Limit to 4.2 V
5. Set Input Current Limit to 500 mA
6. Set Charge Voltage Limit to 4.208 V
7. Set Fast Charge Current, ICHG to 512 mA
8. Set Pre-Charge Current to 256 mA
9. Deselect Enable Termination (see the following image)
10. Click the Read button twice
Observe
→ Everything normal at FAULT box
Observe
→ D1 (STAT) is on, except the bq24192i/292iEVM
Observe
→ D2 (/PG) is on for bq24190/192/192i/193/196/292iEVM
2.3.2.2
Enable Load#1 from
step 4. Measure the voltage across J2 at two different points:
Measure
→ V(J2(SYS), J2(GND)) = 3.65 V ±300 mV
Measure
→ V(J2(BAT), J2(GND)) = 2.5V ±200 mV
