PBTL mode. Only PWM_A input is used.
Protection works similarly to BTL mode (2). Only
difference in SE mode is that OUT_X is Hi-Z

Protection system work similarly to BTL mode
(2) (0, 0, 0); however the PWM input protection

2 channels BTL output
is disabled. Also, overcurrent detection will be
more sensitive and will latch if an error occurs.

(1)
The 1N and 2N naming convention is used to indicate the required number of PWM lines to the power stage per channel in a specific
mode.
(2)
An overload protection (OLP) occurring on A or B causes both channels to shut down. An OLP on C or D works similarly. Global errors
like overtemperature error (OTE), undervoltage protection (UVP), and power-on reset (POR) affect all channels.
PARAMETER
TAS5132DDV
RθJC (°C/W)—2 BTL or 4 SE channels (8 transistors)
1.4
RθJC (°C/W)—1 BTL or 2 SE channel(s) (4 transistors)
2.6
RθJC (°C/W)—(1 transistor)
8.7
Pad area(2)
15 mm2
(1)
JC is junction-to-case, CH is case-to-heatsink.
(2)
RθCH is an important consideration. Assume a 2-mil thickness of typical thermal grease between the pad area and the heatsink. The
RθCH with this condition is 2.5°C/W for the DDV package.
