In addition, a digital programmable time-out function protects the LED in case of a wrong

command from the microcontroller. 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.

Dedicated I²C commands allow to separately program the current intensity in flash and torch

mode using exponential steps. An auxiliary output controls an optional red LED to be used

as a recording indicator.

The device is packaged in 3x3 mm TFBGA25 with 1 mm height.
