3.2.3 Forward/Charge/Sink Mode Verification
Use the following steps for forward/charge mode verification with the EVM default settings per the CELLS, VCHG and ICHG pin resistors:
- Turn on PS #1 set to 12V if not
already on. In the EVM software, click
twice. Verify that- All Fault and Status registers do not report any fault conditions.
-
PG_STAT reports Power Good
-
CHARGE_STAT reads Fast Charge
-
STAT LED is on and not flashing
- To confirm pre-charge regulation
(see Section 2.4), take DMM
measurements as follows:
- Measure → V(BAT) (SRN-TP14 and AGND) = 5V ±0.1V.
- Measure → I(BAT) = 100mA ±50mA.
- To confirm battery fast charge current regulation, increase
Load #1 to 7.6V and take DMM measurements as follows:
- Measure → V(BAT) (BAT-TP13 and AGND) = 7.6V ±0.1V.
- Measure → I(BAT) = 1A ±100mA.
- To confirm input current limit operation, in the EVM software on
the 16-bit tab, lower IINDPM current to 500mA and then take DMM measurement (
or PS #1 measurement if accurate) as follows:
- Measure → I(VIN) = 500mA ±200mA.
-
Verify that IINDPM_STAT register reports IINDPM Active
