Equipped with brightness adjustment function! Multi-channel LED driver for vehicle-mounted tail stop lamp.
The IS32LT3181 is an LED driver for automotive rear lights that supports an external option of a PMOS FET to stabilize the voltage of the LEDs and improves thermal power consumption characteristics. It features six programmable linear constant current sources, allowing the current of the six LED channels to be adjusted between 10mA and 75mA with just a single external resistor. With the built-in pulse width modulation (PWM) control, it allows selection between two brightness levels: the brightest stop state (PWM disabled) and a slightly brighter state for standard tail lighting (PWM enabled). 【Features】 - Simplifies automotive LED light systems and enhances reliability - Improves thermal power consumption characteristics - Equipped with thermal shutdown functionality - Protects from the worst thermal conditions - Controls the slew rate to minimize EMI noise *For more details, please refer to the PDF document or feel free to contact us.
