For LED dimming a quasi logarithmic duty cycle Digital voltage range VDD 3.3V or 5.0V is following the physiology of the human eye. With 3 Low standby current < 1A 50C PWM sources color LEDs can be driven in 3-color LED Low output leakage < 5A 13V, RT mode (245Hz PWM). The Relay PWM mode automati- SPI interface with diagnostics cally adjusts the PWM to an effective supply voltage of Open load detection typ. 11V.
