ALD8100 and ALD9100 Series MOSFETs

ALD quad supercapacitor auto-balancing (SAB™) MOSFET array

Image of Advanced Linear Devices, Inc.'s ALD8100/ALD9100Advanced Linear Devices offers the ALD8100 and ALD9100 family of Supercapacitor Auto Balancing-MOSFETs, or SAB™ MOSFETs, are EPAD® MOSFETs designed to address leakage balance of supercapacitors connected in series. Supercapacitors, also known as ultracapacitors or supercaps, when connected two in series, can be balanced with an ALD9100 dual package. Supercaps connected two, three, or four in series can be balanced with an ALD8100 quad package.

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, 3, and 4-cell series-connected supercaps
  • Scalable to larger supercap stacks and arrays
  • Near-zero additional leakage currents
  • Zero leakage at 0.3 V below rated voltages
  • Balances with series-connect and parallel-connect
  • Leakage currents are exponential function of cell voltages
  • Active current ranges from < 0.3 nA to > 1000 μA
  • Always active, always fast response time
  • Minimizes leakage currents and power dissipation
Applications
  • Series-connected supercapacitor cell-leakage balancing
  • Energy harvesting
  • Zero-power voltage divider at selected voltages
  • Matched current mirrors and current sources
  • Zero-power mode maximum voltage limiter
  • Scaled supercapacitor stacks and arrays
