2 Description
The BCR450 is a LED driver IC optimized for usage with an external power transistor for driving LEDs above
100 mA. For currents up to 85 mA the BCR450 can be used in stand alone operation. The output current level can
be adjusted with an external sense resistor.
The IC can be switched on and off by an external signal, which is also suitable to regulate brightness of the LEDs
by PWM dimming.
The precise internal bandgap stabilizes the circuit and provides stable current conditions over temperature range.
Additional features are included to protect the LEDs from overload, short circuit events as well as from over
voltage. The LEDs can be also protected against thermal overload by thermally coupling the LEDs to the BCR450.
