Texas Instruments · Audio Amplifiers · HTSSOP-28

TPA3136D2PWPR from Texas Instruments, in a HTSSOP-28. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 SD input Shutdown logic input for audio amp (LOW = outputs Hi-Z, HIGH = outputs enabled), TTL logic levels with compliance to AVCC.
2 FAULT tri_state Open drain output used to display short circuit or dc detect fault status, voltage compliant to AVCC.
3 LINP input Positive audio input for left channel, biased at 3 V.
4 LINN input Negative audio input for left channel, biased at 3 V.
5 NC unconnected No Connect pin, can be shorted to PVCC, shorted to GND, or left open.
6 NC unconnected No Connect pin, can be shorted to PVCC, shorted to GND, or left open.
7 AVCC power_in Analog supply voltage.
8 GND power_in Analog signal ground.
9 GVDD power_out High-side FET gate drive supply output with nominal voltage of 7 V.
10 PLIMIT input Power Limiter Control pin, virtual output rail is approximately 4 times the voltage at this pin.
11 RINN input Negative audio input for right channel, biased at 3 V.
12 RINP input Positive audio input for right channel, biased at 3 V.
13 NC unconnected No Connect pin, can be shorted to PVCC, shorted to GND, or left open.
14 PBTL input Parallel BTL mode select pin: LOW = Stereo BTL mode, HIGH = Mono PBTL mode.
15 PVCC power_in Power supply for right channel H-bridge, right and left channel power supplies are connected internally.
16 PVCC power_in Power supply for right channel H-bridge, right and left channel power supplies are connected internally.
17 BSPR bidirectional Bootstrap input/output for right channel positive high-side FET, connect 0.22 µF capacitor from BSPR to OUTPR.
18 OUTPR output Class-D H-bridge positive output for right channel.
19 GND power_in Power ground for the H-bridges.
20 OUTNR output Class-D H-bridge negative output for right channel.
21 BSNR bidirectional Bootstrap input/output for right channel negative high-side FET, connect 0.22 µF capacitor from BSNR to OUTNR.
22 BSNL bidirectional Bootstrap input/output for left channel negative high-side FET, connect 0.22 µF capacitor from BSNL to OUTNL.
23 OUTNL output Class-D H-bridge negative output for left channel.
24 GND power_in Power ground for the H-bridges.
25 OUTPL output Class-D H-bridge positive output for left channel.
26 BSPL bidirectional Bootstrap input/output for left channel positive high-side FET, connect 0.22 µF capacitor from BSPL to OUTPL.
27 PVCC power_in Power supply for left channel H-bridge, right and left channel power supplies are connected internally.
28 PVCC power_in Power supply for left channel H-bridge, right and left channel power supplies are connected internally.
29 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
