Pin Functions

PINI/O/P(1)DESCRIPTION
NAMENO.
OUTPL1OClass-D H-bridge positive output for left channel.
BSPL2PBootstrap supply (BST) for positive high-side FET of the left channel.
PVCCL3PPower supply for left channel H-bridge. Right channel and left channel power supply inputs are connected internally.
SD/FAULT4IOTTL logic levels with compliance to AVCC. Shutdown logic input for audio amp (LOW, outputs Hi-Z; HIGH, outputs enabled). General fault reporting includes Over-Temp, Over-Current, and DC Detect. SD/ FAULT= High, normal operation, SD/ FAULT= Low, fault condition. Device will auto-recover once the OT/OC/DC Fault has been removed.
LINP5IPositive audio input for left channel. Biased at 2.5 V. Connect to GND for PBTL mode.
LINN6INegative audio input for left channel. Biased at 2.5 V. Connect to GND for PBTL mode.
GAIN_SEL7IGain select least significant bit. TTL logic levels with compliance to AVDD. Low = 20-dB Gain, High = 26-dB Gain, Floating = 26-dB Gain.
MODE_SEL8IMode select least significant bit. TTL logic levels with compliance to AVDD. Low = BD Mode with UV Threshold = 7.5 V, High = 1SPW Mode with UV Threshold = 3.4V, Floating = 1SPW Mode with UV threshold = 3.4V.
AVCC9PAnalog supply.
AGND10PAnalog signal ground.
GVDD11OFET gate drive supply. Nominal voltage is 5 V.
PLIMIT12IPower limiter level control. Connect a resistor divider from GVDD to GND to set power limit. Connect directly to GVDD for no power limit.
RINN13INegative audio input for right channel. Biased at 2.5 V.
RINP14IPositive audio input for right channel. Biased at 2.5 V.
MUTE15IMute signal for fast disable/enable of outputs (HIGH = outputs Hi-Z, LOW = outputs enabled). TTL logic levels with compliance to AVCC.
PVCCR16PPower supply for right channel H-bridge. Right channel and left channel power supply inputs are connected internally.
BSPR17PBootstrap supply (BST) for positive high-side FET of the right channel.
OUTPR18OClass-D H-bridge positive output for right channel.
PGND19PPower ground for the H-bridges.
OUTNR20OClass-D H-bridge negative output for right channel.
BSNR21PBootstrap supply (BST) for negative high-side FET of the right channel.
BSNL22PBootstrap supply (BST) for negative high-side FET of the left channel.
OUTNL23OClass-D H-bridge negative output for left channel.
PGND24PPower ground for the H-bridges.
Thermal PadPConnect to GND for best thermal and electrical performance
