Infineon BCR431UXTSA1

Infineon’s BCR431U is a linear LED driver IC in a small SOT23-6 package regulating the LED current in standalone operation without any external power transistor. It is suitable for driving currents up to 37mA and the IC supply voltage ranges from 6V up to 42V. The LED current level can be adjusted by connecting a high-ohmic resistor Rset to pin RS. The voltage drop at the integrated LED driver stage is 200mV max. at 37mA improving the overall system efficiency and providing extra voltage headroom to compensate for tolerances of LED forward voltage and supply voltage. Despite temperature changes, the driving current is always under control. Thanks to a smart temperature controlling circuit which is reducing the LED current when the junction temperature of BCR431U is very high.

Symbol Views

(not all views will be available for every part)

Normal: Standard and most popular representation of schematic symbol

ALT_1 (IEEE view): Symbol representation in a way that is more graphical in explaining what the purpose of each pin is. For connectors and most discretes (as we use these views) it is simply an alternate view for people to use depending on the situation. For instance connectors can be generally an input, an output or neither. Resistors can be vertical or horizontal.

ALT_2 (demorgan): Demorgan is a name for an equivalent Gate structure. so for instance an AND gate and an OR gate can be represented by its Demorgan equivalent of a NOR gate.

Sometimes a device is fractured into multiple symbols (often for high pin count parts). If that is the case, you can preview the different symbols that make up the device by selecting them in this drop down.
