NSL21611
Overview
The NSL21610/1 is an automotive-grade single-channel linear constant current LED driver, with up to 450 m A current capability. Wide supply voltage up to 40 V enables NSL21610/1 a good fit for automotive battery directly powered application. For linear-type constant current LED driver, thermal dissipation limit is a mon issue to prevent it to be applicable for larger current conditions. By implementing a unique thermal balancing design, the NSL21610 is able to enlarge the output current capability with an automatic power balancing loop between the output channel and the external shunt resistor. It can address the thermal dissipation limit issue effectively with the majority of power conducted on the external shunt resistor, instead of the device itself. The NSL21610/1 is able to support full diagnostics including the LED open-load and short-to-GND detection. With different FAULT bus connections, the NSL21610/1 can realize either “all off if one fails” or “others remain on if...
