Notes: 1) The SAB MOSFET Output Current (IOUT) = Drain Source ON Current (IDS(ON)) and is the maximum current available to
offset the supercapacitor leakage current.
2) The Input Voltage (VIN) = Drain Gate Source Voltage (VGS = VDS) and is normally the same as the voltage across the
supercapacitor.
Selection of an SAB MOSFET device depends on a set of desired voltage vs. current characteristics that closely match the supercapacitor
operating VIN voltage and IOUT currents that provide the best leakage and regulation profile of a supercapacitor load. The table lists VIN
which corresponds to different supercapacitor load voltages. At each VIN = VGS = VDS bias voltage, a corresponding IOUT, Drain Source
ON Current, IDS(ON), is produced by a specific SAB MOSFET, which is equal to the amount of current available to compensate for
supercapacitor leakage current inbalances. This current results in an Equivalent ON Resistance RDS(ON) across a supercapacitor cell.
Selection of an SAB MOSFET part number operating at maximum supercapacitor operating voltage at an IOUT that corresponds to the
maximum supercapacitor leakage current offer the best possible tradeoff between leakage current balancing and voltage regulation.
