3.3.3 Charge Current and AC Current Regulation (DPM)

  1. Connect Load #2 in series with a current meter (multimeter) to J3 (BAT, GND). Make sure a voltage meter is connected across J2 (BAT, GND). Turn on Load #2. Use the constant voltage mode. Set output voltage to 10.5V.
  2. Connect the output of Load #1 in series with a current meter (multimeter) to J1 (SYS, GND). Make sure a voltage meter is connected across J1 (SYS, GND). Turn on the power of Load #1.
  3. Type “2944” (mA) in ChargeCurrent Register and click OK.
    This sets the battery charge current regulation threshold to 2.944A.
    • Measure → IBAT = 3000mA ±300mA
    • Measure → V[TP14(IIADP)] = 340mV ±40mV
  4. Set Load #1 current to 3.0A ±50mA but disable the output. Make sure ISYS = 0A ±10mA. Enable the output of Load #1.
    • Measure → ISYS = 3000mA ±300mA
    • Measure → IBAT = 1800mA ±300mA
    • Measure → IIN = 4100mA ±400mA
    • Measure → V[TP14(IADP]) = 820mV ±100mV
  5. Turn off the Load #1.
    • Measure → ISYS = 0 ±100mA
    • IBAT = 3000mA ±300mA
