6 / 33 page  Description (continued) STCF06 6/33 1 Description (continued) 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. |
