Diodes’ AL5958Q matrix LED driver integrates a 48-channel constant-current supply and 16 N-channel MOSFET switches for automotive dynamic lighting. Two cascade-connected drivers assist as much as 32 scans, well-suited for narrow-pixel mini- and micro-LED shows that use a number of RGB LEDs to ship animated lighting results and knowledge.
The AEC-Q100 certified driver employs multiplex pulse density modulation (M-PDM) management to boost the refresh fee of dynamic scanning programs with out rising the grayscale clock frequency or introducing EMI. Constructed-in matrix show command features scale back processing overhead on the native MCU. These features embody computerized black-frame insertion, ghost elimination, and suppression of shorted-pixel caterpillars.
Working from a 3-V to 5-V enter, the AL5958Q’s 48 constant-current outputs provide as much as 20 mA per LED channel string. Present accuracy between channels and matching throughout units is usually ±1.5%.
The AL5958Q LED driver prices $1.60 every in numerous 2500 models.
