The LED Flash Click Board functions as a high power LED photographic flash lamp, and carries the CAT3224 flash LED driver. The click is designed to run on a 5V power supply. It communicates with the target microcontroller over the following pins on the MikroBUSline: AN, RST, PWM, and INT.

Product Details


CAT3224 features

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 4A 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 driver also 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.The CAT3224 has a shutdown mode that is so low that ON Semiconductor can safely call it "zero" mode. In this mode, it typically uses only 1A.

Information about the LED indicatorsOn the LED Flash click there are three different LED indicators, here is how they operate:.
