Forward/Charge/Sink Mode Verification

Use the following steps for forward/charge mode verification with the EVM default settings per the ILIM_HIZ, CELLS, VCHG and ICHG pin resistors:

  1. Turn on PS #1 set to 12V if not already on. In the EVM software, click Read/Read All registers 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

  2. To confirm pre-charge regulation, take DMM measurements as follows:
    • Measure → V(BAT) (SRN-TP14 and AGND) = 5V ±0.1V.
    • Measure → I(BAT) = 100mA ±50mA.
  3. 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.
  4. To confirm input current limit operation, in the EVM software, 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
