Use the following steps for charger mode verification:
PS #1 should be on from Section 2.4.1. In the EVM software, click twice.
Verify that all Fault statuses read "Normal"
To confirm SYS voltage regulation, enable Load #1 (see Section 2.2) and take DMM measurements as follows:
Measure → VSYS (SYS-TP14 and PGND-TP27 or TP28 or TP29) = 3.65V ±0.3V
Measure → VBAT (BAT-TP13 and PGND-TP27 or TP28 or TP29) = 2.5V ±0.2V
Measure → IBAT = 240mA ±50mA
To confirm battery charge current regulation, change Load #1 to 3.7V and take DMM measurements as follows:
Measure → VSYS (SYS-TP14 and PGND-TP27 or TP28 or TP29) = 3.8V ±0.3V
Measure → VBAT (BAT-TP13 and PGND-TP27 or TP28 or TP29) = 3.7V ±0.2V
Measure → IBAT = 480mA ±100mA
To confirm input current limit operation, in the EVM software on the 16-bit tab, set fast charge current to 1040mA and then take DMM measurement ( or PS #1 measurement if accurate) as follows:
