3.2.4 Boost Mode Verification

Use the following steps for boost mode verification:

  1. Turn off and disconnect PS #1.
  2. Set Load #1, the battery simulator, to 3.7V and 2A current limit.
    Note: If Load #1 connected from BATTERY-J4(3) to GND-J4(1) is not a four quadrant supply, then remove Load #1 and use PS #1, set to 3.7V, 2A current limit and connect to BATTERY-J4(3) and GND-J4(1).
  3. In the EVM software on the 16-bit tab, confirm that VOTG, the OTG regulation voltage, is set to 5100mV and IOTG, the OTG current limit, is set to 1500mA.

  4. In the EVM software on the 8-bit tab, disable watchdog then check EN_OTG.

  5. Connect Load #2 across VPB-J3(1) and PGND-J3(2) or VIN-J1(2) and PGND-J1(1)
  6. Set Load #2 to 500mA constant current load and the turn on the load.
  7. To confirm the VOTG regulation,
    • Measure→ VBUS = 5100mV ± 155mV
  8. Turn off and disconnect the power supply.
  9. Remove Load #2 from the connection.
