The TAS5441QPWPRQ1 is an AEC‑Q100 Grade 1 qualified mono Class‑D audio amplifier from Texas Instruments, housed in 16‑pin HTSSOP‑PWP tape‑and‑reel package, delivering up to 22 W output power into 4‑ohm speaker load under 14.4 V automotive battery supply. Supporting 4.5 V‑18 V input voltage range, this device integrates ISO‑7637‑2 40 V load‑dump protection, I2C‑based speaker diagnostic and multi‑layer fault detection, well‑suited for harsh automotive electrical environments with start‑stop battery fluctuation conditions.
Key Features & Applications
● AEC‑Q100 Grade 1 automotive qualification with‑40 °C to 125 °C operating temperature, satisfying strict vehicle component reliability standards.
● 22 W maximum BTL output power into 4 Ω load, up to 85% high conversion efficiency to minimize thermal dissipation for compact automotive PCBs.
● Built‑in 40 V load‑dump protection, over‑voltage, under‑voltage, short‑circuit and thermal shutdown, plus real‑time speaker open/short fault reporting via I2C interface.
● Differential analog audio input, adjustable switching frequency for AM‑band interference avoidance, non‑blocking I2C communication even under standby mode with ultra‑low quiescent standby currentMouser.
This automotive‑grade audio amplifier is widely implemented for automotive eCall emergency call units, vehicle telematics modules, instrument cluster audio alert systems, entry‑level car infotainment subsystems, acoustic vehicle warning units and on‑board voice prompt equipment that requires robust fault diagnosis and high anti‑interference capability for 12 V vehicle power rail.
FAQ
Q: Does TAS5441QPWPRQ1 need external load‑dump clamping circuit?
A: No, internal 40V load‑dump protection meets ISO‑7637‑2 to cut extra peripheral components. 
Q: Is output LC filter mandatory?
A: Yes, external LC low‑pass filter is required to suppress PWM carrier noise and reduce EMI emissions.
