TAS5421QPWPRQ1
Texas InstrumentsTAS5421QPWPRQ1 is a mono Class-D automotive audio amplifier from Texas Instruments in HTSSOP-16 (PWP), supplied on tape and reel — a single-channel BTL amplifier rated 22 W into 4 Ω at 10% THD+N from a 4.5 V to 18 V supply, with 40 V load-dump protection for direct battery connection in eCall, telematics and instrument-cluster audio. I2C load diagnostics report open- and short-load faults to the host, which is what makes this part the default eCall speaker driver: the emergency-call audio path can be tested on the production line and monitored in the field. It is AEC-Q100 Grade 2 qualified over -40 °C to +125 °C, and TI lists the orderable code as Active. Selection advice: this QPWPRQ1 code is the HTSSOP-16 reel form — size the thermal design against the 22 W test conditions in the datasheet rather than any family headline, and note the MSL Level-3 handling requirement on the current TI orderable page. Parameters verified against Texas Instruments documentation.
