3.3.4 Hybrid Boost Mode

Use the following steps for hybrid boost mode:

  1. Enter “1A44” in ChargeOption3 value to enable the hybrid boost function
  2. Change Load #2 with PS#2. Make sure a voltage meter is connected across J2 (BAT, GND).
  3. Enable the output of PS#2. Make sure the output voltage is 10V ±500mV and 3A current limit.
  4. Set Load #1 load current to 5.0A ±50mA. Enter boost mode.
    • Measure → ISYS = 5000mA ±500mA
    • Measure → IBAT = –2000mA ±600mA
    • Measure → IIN = 4100mA ±400mA
    • Measure → V[TP15(IIDCHG)] = 270mV±100mV
  5. Set Load #1 load current to 0.5A ±50mA. Exit boost mode. Back to charging mode.
    • Measure → ISYS = 500mA ±50mA
    • Measure → IBAT = 3000mA ±300mA
    • Measure → IIN = 2100mA ±400mA
