Observation and measurements
- SRC : Equal to the cold-start voltage during the cold-
start phase. Regulated at the selected MPPT percent-
age of
Voc when cold start is over (see Figure 6). Be
careful that the cold-start phase time will shorten with
the input power. Limit it to ease the observation.
- BATT : Starts to charge when the cold-start phase is over
(see Figure 6).

3.5 Dual-cell supercapacitor balancing circuit
This test allows users to observe the balancing circuit behavior
that maintains the voltage on BAL equilibrated.
Setup
1. Following steps 1 and 2 explained in Section 2.1 and re-
ferring to Figure 1, configure the board in the desired
state. Plug the jumper linking ”BAL” to ”ToCN”.
2. BATT : Plug capacitor C1 between the positive (+) and
the BAL pins and a capacitor C2 between BAL and the
negative (-) pins.
Select C1
6
= C2 such that:
- C1 & C2 > 1 mF
-
C2 ∗ Vchrdy

≥
0 . 9 V
3. SRC : Plug your source element to start the flow of power
to the system.
Measurements
- BAL : Equal to half the voltage on BATT .
