3.3.5 Battery-only Boost Mode

The setup for battery-only boost selection follows:

  1. Disconnect PS#1 from J2 (VIN,GND)
  2. Enter “00C0” in ChargeOption2 value to enable the battery-only boost function
  3. Enter “0108” in ChargeOption0 value to disable low power mode and disable the watchdog timer.
  4. Enter “2800” in MinSysVoltage value to set the entry threshold for battery boost to 10.24V.
  5. Reduce the voltage of PS#2 to 9.0V to enter battery-only boost mode
    • Measure → V[TP3(VBATT)] = 9.0V ±300mV
    • Measure → V[TP2(VSYS)] = 12.0V ±600mV
