Description:

4 Amp Supercapacitor Flash LED Driver

Features

* two matched current sources. External resistors provide the adjustment for the maximum flash mode current (up to 4 A) and the torch mode current (up to 400 mA). A built
* in safety timer automatically terminates the flash pulse beyond a maximum duration of 300 ms. In addition to thermal shutdo

Applications

* Ideal for Li
* ion battery
* powered systems, it delivers up to 4 A LED flash pulses, far beyond the peak current capability of the battery. Dual
* mode 1x/2x charge pump charges the stacked supercapacitor to a nominal voltage of 5.4 V, while an active balance control circuit ensu
