NSL21912 is an automotive high-side LED driver with a supply voltage range of 3.8V to 20V and a current output capability of 100mA per channel. The device supports 2-bit global and 6-bit individual current settings, and flexible 12-bit PWM dimming.NSL21912 features a low dropout voltage requirement (700mV Max.@50mA) and supports automatic thermal sharing via VS shunt resistors, providing excellent thermal performance. NSL21912 supports multiple regulations along with LED open-circuit, short-to-ground, and single LED short-circuit diagnostics. It integrates a configurable watchdog and programmable EEPROM, allowing NSL21912 to flexibly configure fail-safe mode for different applications when the MCU connection is lost.NSL21912 supports the UART-based digital interface for a wide range of control and diagnostic features, with a maximum of 16 NSL21912 devices on a single bus.
