Description (continued)

Hard and soft-triggering of flash are both supported. The device includes many functions to

protect the chip and the power LED, such as: a soft start control, chip over temperature

detection and protection, as well as opened and shorted LED detection and protection.

Besides, a digital programmable time out function protects the LED in case of a wrong

command from the µP. An optional external NTC resistor is supported to protect the LED

against over heating. In mobile phone applications, it is possible to reduce immediately the

flash LED current during the signal transmission using the TMSK pin. This saves battery life

and gives more priority to supply RF transmission instead of flash function.

It is possible by I²C to separately program the current intensity in flash and torch mode using

exponential steps. An auxiliary output can control an optional red LED to be used as a

recording indicator.

The device is packaged in 3x3 mm µTFBGA25 with a height less than 1 mm.
