On-chip short-circuit and thermal protection are included, plus a shutdown pin for power management. The differential inputs reject ground noise common in single-supply designs, and the depop circuitry suppresses turn-on clicks that would otherwise require external muting FETs. These integrated features reduce BOM count compared to a discrete Class D implementation.
The TPA2001D2PWP delivers 1W per channel into an 8Ω load, stereo configuration.
Yes, the TPA2001D2PWP includes shutdown, short-circuit protection, and thermal protection as built-in features.
The TPA2001D2PWP is the same die in a different package (HTSSOP vs TSSOP). Verify the footprint and thermal pad compatibility before substituting; the electrical characteristics are identical.
