Test Summary
2.3.2 Charge Voltage and Current Regulation of V
IN
and Device ID Verification
Follow the steps and verify the outputs and IC for the EVM.
2.3.2.1 Software setup (all of Section 2.3.2.1 is done in the GUI):
1. Device address: bq24195/L (6B)
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 bq24192IEVM
2.3.2.2 Enable Load#1 from Section 2.2 step 4. Measure the voltage across J2 at two different points:
V(J2(SYS), J2(GND)) and V(J2(BAT), J2(GND))
Measure → V(J2(SYS), J2(GND)) = 3.65 V ±300 mV
Measure → V(J2(BAT), J2(GND)) = 2.5V ±200 mV
