Pin Functions

PINI/O/P(1)DESCRIPTION
NAMENUMBER
SD 1 I Shutdown logic input for audio amp (LOW = outputs Hi-Z, HIGH = outputs enabled). TTL logic levels with compliance to AVCC.
FAULT 2 O Open drain output used to display short circuit or dc detect fault status. Voltage compliant to AVCC. Short circuit faults can be set to auto-recovery by connecting FAULT pin to SD pin. Otherwise, both short circuit faults and dc detect faults must be reset by cycling PVCC.
LINP 3 I Positive audio input for left channel. Biased at 3 V.
LINN 4 I Negative audio input for left channel. Biased at 3 V.
NC 5, 6, 13 I No Connect Pin. Can be shorted to PVCC or shorted to GND or left open.
AVCC 7 P Analog supply
GND 8 P Analog signal ground.
GVDD 9 O High-side FET gate drive supply. Nominal voltage is 7 V.
PLIMIT 10 I Power Limiter Control pin
RINN 11 I Negative audio input for right channel. Biased at 3 V.
RINP 12 I Positive audio input for right channel. Biased at 3 V.
PBTL 14 I Parallel BTL mode select pin. L=Stereo BTL mode, H=Mono PBTL mode
PVCC 15, 16 P Power supply for right channel H-bridge. Right channel and left channel power supply inputs are connected internally.
BSPR 17 I Bootstrap I/O for right channel, positive high-side FET.
OUTPR 18 O Class-D H-bridge positive output for right channel.
GND 19 P Power ground for the H-bridges.
OUTNR 20 O Class-D H-bridge negative output for right channel.
BSNR 21 I Bootstrap I/O for right channel, negative high-side FET.
BSNL 22 I Bootstrap I/O for left channel, negative high-side FET.
OUTNL 23 O Class-D H-bridge negative output for left channel.
GND 24 P Power ground for the H-bridges.
OUTPL 25 O Class-D H-bridge positive output for left channel.
BSPL 26 I Bootstrap I/O for left channel, positive high-side FET.
PVCC 27, 28 P Power supply for left channel H-bridge. Right channel and left channel power supply inputs are connected internally.
Thermal Pad P Connect to GND for best thermal and electrical performance.
I = Input, O = Output, P = Power
