Measurement Procedures
Consumption current 1
V3 = V
CC
, V4 = 0V. Next, measure A5 current value Icc1 when V3 is changed
from V
CC
0V.
V3 = Vd = V
CC
. Measure A6 current value I
CC2
at this time.
V3 = V
CC
, V4 = 0V. Measure T7 voltage V
O
at this time.
V3 = Vcc, V4 = 0V. Set V7 voltage 1V lower than T7 (output voltage) potential
and set SW7 to B. Measure T8 voltage V
CL
at this time.
V3 = V
CC
, V4 = 0V, SW6: C. V7 = 4.5V, SW7: B. Measure A7 current value
I
CEL1
at this time.
V3 = V4 = V
CC
= 0V, SW6: C. V7 = 4.5V, SW7: B. Measure A7 current value
I
CEL2
at this time.
Measure A4 current value I
SW1
when V4 = 0V.
V3 = V
CC
. Charge: ON (V
L1
) when V4 potential is varied and T7 voltage is the
prescribed output voltage; Charge OFF (V
H1
) when 0 ~ 0.05V.
V3 = V4 = 0V. Set V7 voltage 1V lower than T7 (output voltage) potential, and
SW7: B.
Next gradually lower V7 voltage; V7 voltage is L
V
when A7 current value is
within ±10μA.
Measure A3 current value I
SW2
when V3 = 0V.
V4 = 0V, V7 = 1V, SW7: B. Low voltage detection circuit: ON (V
L2
) when V3
voltage is varied and A7 current value is within ±10μA; low voltage detection
circuit: OFF (V
H2
) otherwise.
V3 = V
CC
, V4 = 0V. Measure A2 current value I
LV
when V3 is changed from
Vcc 0V.
