2.4.4 Boost Mode Verification

Use the following steps for boost mode verification:

  1. Turn off and disconnect PS1.
  2. Set Load #1 to 3.7V and 2A current limit.
    Note:

    If Load #1 connected from BATTERY-J4(3) to PGND-J4(1) is not a four quadrant supply, remove Load #1 and use PS1 (disconnected in 8.4.1), set to 3.7V, 2A current limit and connect to BATTERY-J4(3) to PGND-J4(1).

  3. In the EVM software, check GUID-948712F2-3122-4176-BAE9-A44CF6BB0A8E-low.gif.
  4. Connect Load #2
    • For BQ25619 (BMS025-005): across VPB-J3(1) and PGND-J3(2).
    • For all others: across VIN-J1(2) and PGND-J1(1).
    • For BQ25619, measure VPB (VPB-TP14 and PGND-TP32) = 5.0V ±0.2V.
    • For all others, measure VBUS (VBUS-TP12 and PGND-TP31) = 5.0V ±0.2V.
  5. Turn off and disconnect power supply.
  6. Remove Load #2 from connection.
