Description (continued)
All the functions of the device are controlled through the I
2
C which helps bus that allows to
reduce logic pins on the package and to save PCB tracks on the board. 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
2
C 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 QFN 4x4 20L with a height less than 1 mm and in TFBGA25 3x3.
