(1)
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)
PWM_D is used to select between the 1N and 2N interface in PBTL mode (Low = 1N; High = 2N). PWM_D is internally pulled low in
PBTL mode. PWM_A is used as the PWM input in 1N mode and PWM_A and PWM_B are used as inputs for the 2N mode.
(3)
PPSC detection system disabled.
PARAMETER
TAS5342LDDV
RθJC (°C/W)—2 BTL or 4 SE channels
1.8
RθJC (°C/W)—1 BTL or 2 SE channel(s)
3.6
RθJC (°C/W)—1 SE channel
7.2
Power Pad area(2)
36 mm2
(1)
JC is junction-to-case, CH is case-to-heatsink.
(2)
RθCH is an important consideration. Assume a 2-mil thickness of high performance grease with a thermal conductivity at 2.5W/m-K
between the pad area and the heat sink. The RθCH with this condition is 0.6°C/W for the DDV package.
