The STPA001 is a breakthrough MOSFET technology class AB audio power amplifier designed for high power car radio. The fully complementary P-Channel/N-Channel output structure allows a rail to rail output voltage swing which, combined with high output current and minimized saturation losses sets new power references in the car-radio field, with unparalleled distortion performances.  MOSFET output power stage  2 Ω driving capability  Hi-Fi class distortion  Low output noise  High immunity to RF noise injection  Standby function  Mute function  Automute at min. supply voltage detection  Low external component count  Protections: – Output short circuit to GND, to Vs, across the load – Very inductive loads – Overrating chip temperature with soft thermal limiter – Output DC offset detection – Load dump – Fortuitous open GND – Reversed battery – ESD – Capable to operate down to 6 V (e.g. “Startstop”) The STPA001 can operate down to 6 V and this makes the IC compliant to the most recent OEM specifications for low voltage operation (so called 'start-stop' battery profile during engine stop), helping car manufacturers to reduce the overall emissions and thus contributing to environment protection.

It is available in three different packages, Flexiwatt25 (vertical), Flexiwatt25 (horizontal) and Flexiwatt27. It embeds four independent amplifiers working in class AB, a standby and a mute pin, a clipping detector and diagnostics output and, only for the Flexiwatt27 package, an offset detector pin. The amplifier is fully operational down to a battery voltage of 6 V, without producing pop noise and continuing to play during battery transitions. The STPA001 can drive 2 Ω loads and has a very high immunity to disturbs without need of external components or compensation. It is protected against any kind of short or open circuit, over-voltage and over-temperature. 1.1 Block diagram and application circuit Figure 1.
