Description
The CAT3224 is a very high
current integrated flash LED driver which also supports the charging function for a dual
cell supercapacitor applications.
ion battery
powered systems, it delivers up to 4 A LED flash pulses, far beyond the peak current capabili
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 shutdown and overvoltage protection, the device is fully protected against external resistor programming faults and fully supports reverse output voltage for all conditions. The device is packaged in the ti.
