PWM dimming input allows brightness control independent of the supply rail — the driver acts as a constant-current sink, so dimming resolution is set by the PWM frequency and duty cycle from the host controller. Supply range spans 4.5 V to 40 V, covering common automotive and industrial rails (12 V, 24 V, 36 V). The internal switch handles the full 1.5 A load, so no external MOSFET is needed — the 8-DFN (3x3 mm) package with exposed pad dissipates the heat through the PCB copper plane. Junction temperature rating extends to 150 °C, suitable for under-hood or high-ambient enclosures. Tape-and-reel or cut-tape packaging is available; the reel quantity is standard for this package family. No special handling beyond MSL level typical for DFN packages — confirm the moisture sensitivity level on the reel label before bake-out decisions. ROHS3 compliant.","metaTitle":"STMicroelectronics STCS1PUR Linear LED Driver, 1.5 A, PWM","metaDescription":"STMicroelectronics STCS1PUR linear LED driver, 1.5 A output, PWM dimming, 4.5-40 V supply, 8-DFN package.
