Description: | 4 Amp Supercapacitor Flash LED Driver |
Manufacturer: | ON Semiconductor |
Datasheet: | PDF (192K). Click here to download *) |
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 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 ensures that both capacitor cell voltages remain matched. The nominal charging current to be drawn from the battery is set by an external resistor tied to the RC pin. |
