The AL5958QJCZW76-13 from Diodes Incorporated is an Automotive-Qualified 48-Channel Matrix LED Driver IC designed for automotive lighting systems such as central information displays, cluster displays, head-up displays, grill lights, body mini-LED panels, interior lighting, and rear lighting. It operates with two separate supply voltages—VR (2.8–5 V) and VGB (3–5 V), and delivers up to 20 mA constant current per channel. This AEC-Q100 Grade 1-qualified driver integrates 16 NMOS scan switches for flexible scan sequence and intelligent matrix display functions, including black frame insertion, ghost image suppression, brightness uniformity tuning, and LED fault mitigation.

The AL5958Q features a 16-bit PWM grayscale dimming mechanism enhanced by Multiplex Pulse Density Modulation (M-PDM) technology, which boosts refresh rates without increasing grayscale clock frequency, minimizing EMI interference. It incorporates protection features such as LED open/short detection, grayscale clock watchdog, and undervoltage lockout (UVLO). This RoHS-compliant driver is available in a surface-mount package measuring 9.00 x 9.00 mm.
