The IS32LT3152B-ZLA3-TR from Lumissil Microsystems is an Automotive-Grade Three-Channel Linear LED Driver IC with individual PWM dimming and thermal shunt. It requires an input voltage of 4.5–40 V and can source up to 150 mA per channel with ±4% current accuracy across the full automotive temperature range. This AEC-Q100-qualified LED driver features a maximum dropout voltage of 0.8 V at 150 mA per channel, ensuring efficient operation in 12 V automotive systems. 

The IS32LT3152B-ZLA3-TR integrates comprehensive fault protection, including LED string open/short detection, external UVLO setting, current reference set resistor open/short, shared fault flag for multiple device operation to comply with the “one-fail-all-fail” function, and thermal shutdown. This RoHS-compliant LED driver has a typical shutdown supply current of 18 µA and an operating junction temperature range of -40°C to +125°C. It is available in a surface-mount package that measures 6.4 x 5.1 x 1.2 mm and is ideal for automotive rear lights, stop/taillights, position lights, daytime running lights, turn signals, and interior lighting applications.
