2.4.1 Charge Function

  1. Make sure Equipment Setup steps are followed.
  2. Set Tgt Address to D6(6B)
  3. Write “020A” to charge option 0 register 0x00H.
    Measure → V(J1(VIN)) = 10 V ±0.5 V
    Measure → V(TP28(CHG_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 “0400” to charge current 0x02H.
    Turn on load #1.
    Measure → V(J6(VSYS)) = 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 A
