AL5958Q

AL5958Q is a Diodes Incorporated 48-channel matrix LED driver in a W-QFN9090-76 package — for automotive matrix headlamps and high-segment-count light signatures, driving constant currents of 0.5 mA to 20 mA per channel with 16-bit PWM and support for 0 to 32 scan lines. It is AEC-Q100 Grade 1 qualified for safety-relevant exterior lighting designs. The orderable code is AL5958QJCZW76-13, the wettable-flank 9 x 9 mm WQFN-76 on tape and reel. Selection advice: this is a scanned matrix driver, so channel count, scan count and per-channel current trade against each other and against LED forward-voltage headroom — architect the matrix (rows, columns and any external switches the design needs) from the datasheet application circuit before committing the BOM. Against the AL58818Q and AL58812Q linear drivers on this site, which suit direct-drive segmented lamps, the AL5958Q is the choice when the lamp is a true pixel matrix. Confirm diagnostic coverage and the interface daisy-chain plan for multi-device lamp modules early in the design. Parameters verified against Diodes Incorporated documentation.
