2.4.1 Charge Function

  1. Make sure Equipment Setup steps are followed.
  2. Set Tgt Address to 12(9) for bq25700A or D6(6B) for bq25703A
  3. Write “020E” to charge option 0 register 0x12H (bq25700A) or 0x00H (bq25703A).
    Measure → V(J1(VIN)) = 10 V ±0.5 V
    Measure → V(TP28(CHRG_OK)) = 3 V to 4.5 V
    Measure → V(TP21(REGN)) = 6 V ±1 V
    Measure → V(TP22(ILIM_HIZ)) = 2.2 V
  4. Write “0800” to charge current 0x14H (bq25700A) or 0x02H (bq25703A). Turn on load #1.
    Measure → V(J6(SYS)) = 8.4 V ±0.5 V
  5. Turn on LOAD #2 (VBAT Load).
    Measure → V(J5(VBAT)) = 7 V ±0.5 V
    Measure → I(J5(VBAT)) = 2 A ±0.5 V
