STMicroelectronics
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.
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
