The power DMOS switches with a dedicated slope, which is optimized in terms of EMC emission. Defined slew
rates and edge shaping allow lowest EMC emissions during PWM operation at low switching losses.

Channel 2 and channel 3 can be configured in bulb and LED mode via the SPI registers HWCR.LEDn. During LED
mode following parameters are changed for an optimized functionality with LED loads: On-state resistance
R
and current sense ratio
