Description (continued)
An optional external NTC is supported to protect the LEDs against over heating. In mobile
phone application it is possible to reduce immediately the flash LEDs 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 to separately program the current intensity in flash and torch mode using
exponential steps by I²C. In case of insufficient power from the battery a warning is
generated. An auxiliary output can control an optional red LED to be used as a recording
indicator.
The device is packaged in BGA 3 x 3 mm with 1 mm height.
