The Fast LED Driver ST can be used for optogenetics, retinography and other light stimulating applications controlled by the BioStim system. It can drive any kind of LED directly with calibrated current, independently of the LED model. The LED Driver is compatible either with BioStim Dual-processor Controller or with BioStim Computer Interface. It contains a built-in accurate constant current generator and a high speed gating circuit for extremely fast switching of the LEDs.

There is a very special feature implemented in the design. It is overdrive protection.

A BioStim Controller or a BioStim Computer Interface needed for operation to provide the supply voltage and the control signal for the Fast LED Driver.

Specifications / Technical Data

  • The selectable ranges of the output current: 5 to 55 mA in 11 steps (5 mA each step); 10 to 110 mA in 11 steps (10 mA each step)
  • Compliance voltage of the current generator: 13.5 V
  • Worst-case error of the output current generator: < 2 %
  • Active current sink circuit to eliminate the parasitic charge holding effect of LEDs
  • Overdrive Protection Circuit: the full scale is never overridden
