STPA003
4 x 52 W quad bridge power amplifier with high side driver and
low voltage operation
Datasheet
- production data
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 battery
– ESD
Description
The STPA003 is a MOSFET class AB audio
power amplifier, designed for high-power car
radio. In addition to the outstanding output current
capability and distortion performance, the
STPA003 is extremely robust against several
kinds of fortuitous misconnection.
It is compliant to the most recent OEM
specifications for low voltage operation (the so
called 'start-stop' battery profile during engine
stop).
It includes a DC offset detector and, in
Flexiwatt27 package, a high side driver or a
clipping detector.
