Each of the six outputs delivers up to 50 mA, with the total device current limited by the thermal dissipation of the 10-MSOP package. The linear topology means no inductor or switching noise — the output current is set by an internal current reference, so the LED brightness is consistent across channels without external ballast resistors. ## PWM dimming — colour-stable brightness control The PWM dimming input allows the LED current to be gated on and off with an external PWM signal, typically from a microcontroller or system controller. Because the driver is linear, the PWM switching does not shift the LED colour temperature — the current amplitude during the on-time stays at the full 50 mA level, so the chromaticity remains constant across the dimming range. ## Active lifecycle — no last-time-buy deadline to manage This removes the supply-chain pressure of qualifying a drop-in replacement for a production BOM. ## 10-MSOP footprint — layout for thermal management ## Sourcing this part for a production BOM For volume commitments or scheduled releases, the active lifecycle status means the factory pipeline is open, so lead times are generally predictable.","metaTitle":"MIC4811YMM Linear LED Driver, 6-Ch 50mA PWM Dimming, 10-MSOP","metaDescription":"MIC4811YMM 6-channel linear LED driver from Microchip. 50 mA per channel, PWM dimming, -40 to 125°C junction range.
