Advanced Linear Devices ALD8100xx/ALD9100xx Quad/Dual SAB™ MOSFET Arrays
Advanced Linear Devices ALD8100xx/ALD9100xx Quad/Dual SAB™ MOSFET Arrays are built with production-proven EPAD® technology. The ALD8100xx/ALD9100xx Supercapacitor Auto Balancing (SAB) addresses voltage and leakage-current balancing of supercapacitors connected in series. Supercapacitors, also known as ultracapacitors or super caps, connected in series can be leakage-current balanced by using a combination of one or more devices connected across each supercapacitor stack to prevent over-voltages.
Features
- Simple and economical to use
- Precision factory trimmed
- Automatically regulates and balances leakage currents
- Effective for supercapacitor charge-balancing
- Balances up to 4 supercaps with a single IC package
- Balances 2-cell, 3-cell, 4-cell series-connected supercaps
- Scalable to larger supercap stacks and arrays
- Near zero additional leakage currents
- Zero leakage at 0.3V below rated voltages
- Balances series and/or parallel-connected supercaps
- Leakage currents are exponential function of cell voltages
- Active current ranges from <0.3nA to >1000μA
- Always active, always fast response time
- Minimizes leakage currents and power dissipation
Applications
- Series-connected supercapacitor cell leakage balancing
- Energy harvesting
- Long term backup battery with supercapacitor outputs
- Zero-power voltage divider at selected voltages
- Matched current mirrors and current sources
- Zero-power mode maximum voltage limiter
- Scaled supercapacitor stacks and arrays
