ALD910018SAL

The ALD810018 can balance up to four supercapacitors connected in series, while the ALD910018 is suitable for balancing up to two series-connected supercapacitors.

The precision gate threshold voltage in the Vt mode for the SAB MOSFETs ALD810018/ALD910018 is 1.80V when the gate-drain source terminals are connected together at a drain-source current of IDS(ON) = 1µA.

The ALD810018 and ALD910018 SAB MOSFETs are designed to balance supercapacitors connected in series by providing unique, precise operating voltage and current characteristics for each device. The SAB MOSFETs help prevent over-voltages and leakage currents in series-connected supercapacitors by acting as a variable resistor that controls voltage rise across the supercapacitors. They offer gate threshold voltage precision and can balance up to four supercapacitors for ALD810018 and up to two supercapacitors for ALD910018. The SAB MOSFETs ensure that each supercapacitor in the series maintains the correct voltage levels, preventing issues related to voltage imbalances.
