TPA3136AD2PWPR

Texas Instruments · Audio Power OpAmps · HTSSOP-28-EP

TPA3136AD2PWPR from Texas Instruments, in a HTSSOP-28-EP. 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 the audio amplifier, LOW puts the outputs in Hi-Z and HIGH enables them, with TTL logic levels referenced to AVCC.
2 FAULT output Open-drain output that reports short-circuit or DC-detect fault status and is voltage compliant to AVCC; tie it to SD for automatic short-circuit recovery.
3 LINP input Positive audio input for the left channel, biased at 3 V.
4 LINN input Negative audio input for the left channel, biased at 3 V.
5 NC unconnected No-connect pin that can be shorted to PVCC, shorted to GND, or left open.
6 NC unconnected No-connect pin that can be shorted to PVCC, shorted to GND, or left open.
7 AVCC power_in Analog supply; the recommended supply range for TPA3136AD2 is 8 V to 14.4 V.
8 GND power_in Analog signal ground.
9 GVDD output High-side FET gate drive supply with a nominal voltage of 7 V, which requires a 1-µF capacitor to ground.
10 PLIMIT input Power limiter control pin whose voltage sets the PLIMIT threshold.
11 RINN input Negative audio input for the right channel, biased at 3 V.
12 RINP input Positive audio input for the right channel, biased at 3 V.
13 NC unconnected No-connect pin that can be shorted to PVCC, shorted to GND, or left open.
14 PBTL input Parallel BTL mode select pin: L selects stereo BTL mode and H selects mono PBTL mode.
15 PVCC power_in Power supply for the right-channel H-bridge, connected internally to the left-channel supply input.
16 PVCC power_in Power supply for the right-channel H-bridge, connected internally to the left-channel supply input.
17 BSPR input Bootstrap I/O for the right channel positive high-side FET.
18 OUTPR output Class-D H-bridge positive output for the right channel.
19 GND power_in Power ground for the H-bridges.
20 OUTNR output Class-D H-bridge negative output for the right channel.
21 BSNR input Bootstrap I/O for the right channel negative high-side FET.
22 BSNL input Bootstrap I/O for the left channel negative high-side FET.
23 OUTNL output Class-D H-bridge negative output for the left channel.
24 GND power_in Power ground for the H-bridges.
25 OUTPL output Class-D H-bridge positive output for the left channel.
26 BSPL input Bootstrap I/O for the left channel positive high-side FET.
27 PVCC power_in Power supply for the left-channel H-bridge, connected internally to the right-channel supply input.
28 PVCC power_in Power supply for the left-channel H-bridge, connected internally to the right-channel supply input.
29 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
