The 1N and 2N naming convention is used to indicate the number of PWM lines to the power stage per channel in a specific mode.
(2)
INPUT_C and INPUT_D are used to select between a subset of AD and BD mode operations in PBTL mode.

(1)
RqJC is junction-to-case; RqCH is case-to-heatsink.
(2)
RqCH is an important consideration. Assume a 2-mil (0.051-mm) thickness of thermal grease with a thermal conductivity of 2.5 W/mK
between the pad area and the heat sink and both channels active. The RqCH with this condition is 1.1°C/W for the PHD package and
0.44°C/W for the DKD package.
