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.
