ALD810021
Description
The ALD810021/ALD910021 are members of the ALD8100xx (quad) and ALD9100xx (dual) family of Supercapacitor Auto Balancing MOSFETs, or SAB™ MOSFETs. SAB MOSFETs are built with production proven EPAD® technology and are designed to address voltage and leakage-current balancing of supercapacitors connected in series.
Key Features
- In this mode, input voltage VIN = VGS = VDS
- This VIN, when connected across each supercapacitor in a series, balances each supercapacitor to within its voltage and current limits
- When VIN = 2.10V is applied to an ALD810021/ALD910021, its IOUT is 1µA
- For a 100mV increase in VIN, to 2.20V, IOUT increases by about tenfold
- For an additional increase in VIN to 2.32V for the ALD910021 (2.34V for the ALD810021), IOUT increases one hundredfold, to 100µA
- Conversely, for a 100mV decrease in VIN to 2.00V, IOUT decreases to one tenth of its previous value, to 0.1µA
- Another 100mV decrease in input voltage would reduce IOUT to 0.01µA
