The package is 32-HTSSOP with an exposed pad. ## Short-circuit protection built in Short-circuit protection on the outputs is included — no external crowbar or fuse needed per channel. The chip folds back or shuts down on a fault; it auto-recovers when the fault clears. That saves a few components on the BOM and keeps the board clean for production. No known second-source or pin-compatible alternate from another manufacturer; if you need dual sourcing, the closest functional match is another TI Class D in the same package family, but the pinout differs — verify before swapping.","metaTitle":"TPA3128D2DAP Class D Stereo Amplifier IC, 30W x 2 @ 8Ω","metaDescription":"TI TPA3128D2DAP Class D stereo amplifier, 30W x 2 @ 8Ω, 4.5V-26V supply, -40°C to 85°C, 32-HTSSOP.
