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 D are used to select between a subset of AD and BD mode operations in PBTL mode (1=VREG and 0=AGND)..

RqJC (°C/W) – 2 BTL or 4 SE channels

3.63

2.52

RqJC (°C/W) – 1 BTL or 2 SE channel(s)

5.95

Pad Area (2)

49 mm2

80 mm2

(1)

JC is junction-to-case, CH is case-to-heat sink

(2)

RqCH is an important consideration. Assume a 2-mil thickness of typical thermal grease between the pad area and the heat sink and

both channels active. The RqCH with this condition is 1.22°C/W for the PHD package and 1.02°C/W for the DKD package
