New automotive-grade 12-channel LED driver with local dimming operates in standalone or in I²C bus-driven mode

The ALED1262ZT is a 12-channel 60 mA LED driver tailored to meet requirements for rear combination light applications with graphic animation.

The device features two operating modes (bus-driven or standalone) and independent 7-bit PWM dimming with exponential brightness correction on each channel, making it suitable for rear combination lights and interior lighting systems, where high flexibility is a must.

Housed in a HTSSOP24 package, the ALED1262ZTensures long lasting robustness and stability thanks to diagnostic features such as open-LED detection and over-temperature warning with thermal shutdown.

Expanding range of Automotive qualified LED array drivers

With the addition of the ALED1642GW, our offer of LED array driver products manufactured and qualified to meet and exceed Automotive industry requirements is growing adding new functionalities to the existing range like:

  • individually Pulse Width Modulation (PWM) controlled outputs to implement a 16 grayscale dimming,
  • auto power shut-down/wake-up capability to help minimizing power consumption
  • programmable turn-on and turn-off time to help designer meeting tight Electro Magnetic Compatibility (EMC) constrains

Check out our other Automotive qualified LED array drivers STAP08DP05 (8 channels), STAP16DPPS05 (16 channels) and its higher current counterpart STAP16DPS05
