CAT3224 4 Amp Supercapacitor Flash LED Driver

The CAT3224 is a very high *current integrated flash LED driver which also supports the charging function for a dual *cell supercapacitor applications. Ideal for Li *ion battery *powered systems, it delivers up to 4 A LED flash pulses, far beyond the peak current capabili.

CAT3224 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
