Lithium-ion battery charge control IC MM3635
(Except where noted otherwise Ta=0~45°C, V
Supply current 1
Measure the current of I1-I10 when
R8=(Irapchg=500mA setting) and IF10=500mA.
1. Measure the current of I10 when VF1=0V and VF10=4.2V.
2. Measure the current of I10 when VF10=4.25V
(charge completion mode).
When gradually increasing VF1 from 2.3V to 2.7V under the condition of VF9=3.2V
and VF10=3.2V, the VF1 when I9 exceeds 100µA should be Vpor.
When gradually increasing VF1 from 2.3V to 4.0V under the condition of
VF10=3.2V, the VF1 when V3 changes from H to L should be Vadp.
Measure the current of I9 when VF 9=4.5V to 3.2V after being kept under the
condition of VF10=3.2V and VF9=4.5V and entering into error mode.
Measure the current of I9 immediate after increasing VF1 from
2.3V to 5.0V when VF9=3.2V and VF10=3.2V.
When gradually increasing VF10 from 2.9V to 3.1V under the condition of
VF10=2.5V, the VF10 when |I10| exceeds 530mA should be Vqchgon.
Fast-charge start detection
When gradually decreasing VF10 from 3.1V to 2.7V under the condition
of VF10=3.5V, the VF10 when |I10| falls below 530mA should be
When CVSEL=H, gradually decreasing VF10 from 4.00V to 3.80V, and
when CVSEL=L, gradually decreasing VF10 from 3.90V to 3.70V after
being kept in the condition of VF10=4.25V and entering into charge
completion mode, the VF10 when the charging restarts (|I10|>1mA)
and V3=H to L should be Vrechg1(CVSEL=H), Vrechg2(CVSEL=L).
Measure the voltage of V9 in fast charge mode and when IF10=
-5mA (|IF10|>Ifc). Vchg1=CVSEL=H, Vchg2=CVSEL=L
Charge stop I/O potential
When gradually decreasing VF1 from 4.1V to 4.0V under the
condition of fast charge mode, VF1=4.1V, and VF10=4.0V, the V1-V10
when the charging stops (|I10|<1mA) should be Vdef1.
Charge stop I/O
potential difference 2
When gradually increasing VF1 from 4.0V to 4.1V under the condition
of fast charge mode, VF1=4.0V, and VF10=4.0V, the V1-V10 when the
charging restarts (|I10|>1mA) should be Vdef2.
When gradually increasing VF10 from 4.27V to 4.43V under the condition
of VF10=4.25V, the VF10 when V3 becomes blinking (repeating H L,
charge error mode) should be Vov.
Forced charge current
Measure the current of I10 immediately after increasing VF1
from 2.3V to 5.0V when VF10=3.6V and R8=75k .
Measure the current of I10 when VF10=2.6V and R8=75k .
Measure the current of I10 when VF10=3.6V and R8=75k .
When gradually increasing VF9 from 4.1V to 4.2V under the condition
of VF9=3.6V and VF10=Vqchgon, the |I10| immediately before V3=L to
H and the charging stops (|I10|>1mA) should be Ifc.
