Overview
STPA003 4 x 52 W quad bridge power amplifier with high side driver and low voltage operation Datasheet - production data '!0'03 Flexiwatt25 '!0'03 Flexiwatt27 Features  High output power capability: – 4 x 52 W/4 Ω max.
– 4 x 30 W/4 Ω @ 14.
4 V, 1 kHz, 10 % – 4 x 85 W/2 Ω max.
– 4 x 55 W/2 Ω @ 14.
4V, 1 kHz, 10 %  MOSFET output power stage  Capable to operate in low voltage conditions (e.
g.
: “Start - Stop”)  Excellent GSM noise immunity  Excellent 2 Ω driving capability  Hi-Fi class distortion  Low output noise  Standby function and mute function  Automute at min.
supply voltage detection  Low external component count: – Internally fixed gain (26 dB) – No external compensation – No bootstrap capacitors  On board 0.
4 A high side driver  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 voltage – Fortuitous open GND – Reversed ba...
