Page 3: Circuit Description
The APPEB1012 also includes an inbuilt active balance control which is a feature of the AEM10941 so dual cell supercapacitors can be used as well as single cell supercapacitors. - Page 4 PMIC with MPPT C8, C9 are landing pads for CAP-XX GY cylindrical cells and C10 are the landing pads a CAP-XX prismatic single cell or dual cell part. R7 is a 1Ω resistor designed to allow the input current to be measured, while R14 is a 1Ω...
- Page 5 CAP-XX prismatic supercapacitor – Single cell CAP-XX has 4 main package types for the prismatic line. From the smallest to the biggest they are: Z, A, W and S. The A and Z packages are pin compatible. Pins are reversed between W/S packages and the A/Z packages.

Page 9: Output Mode Selection
Table 4: Example resistor values for typical use Output mode selection APPEB1012 has two output modes, either directly connect the output to the supercapacitor or have the PMIC handle the output based on charge management voltage thresholds This is accomplished by placing the jumper link on the desired section of the 3-pin header labelled OUTPUT, illustrated in figure 8 below. - Page 10 Time (s) Figure 9: Example output voltage operation In figure 9, HA102 is connected to the APPEB1012 and the supercapacitor voltage and output voltage was observed. The system configuration was connected as CFG[2:0] = [0 0 0] such that the PMIC entered custom mode as described in table 3. Custom external resistors were chosen to create the charge management equal to the first row of table 4.
