PRODUCTION DATA.

| PIN | I/O/P(1) | DESCRIPTION | |
|---|---|---|---|
| NAME | NUMBER | ||
| 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. | |
