BCR602 supports use of NPN bipolar transistors and NMOSFETs to cover a wide LED current and power range up to several hundred mA. The LED current is fully scalable by dimensioning an external current sense resistor. BCR602 suppresses the voltage ripple of the power supply driving a constant LED current for better light quality. The LED current can be dimmed by resistors as well as analog or digital PWM voltages connected to the Multi Function Input Output (MFIO) pin. The embedded hot plug protection allows plug in and plug out of any LED load during operation. The overtemperature protection will dim the LED current if the BCR602 junction temperature threshold is exceeded. In this case the LED current will be reduced to 30% of the nominal current. Once the junction temperature drops below the temperature hysteresis nominal LED current is resumed. The BCR602 is a perfect fit for LED applications by combining small form factor with low cost. Through its higher integration, BOM savings and ensuring long lifetime of LEDs, this controller has many advantages compared to discrete solutions. Datasheet 2 Revision 1.1 2018-12-3
