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 I
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.
