EnChip AXPA17388 功放IC 音频功率放大器 替ST TDA7388

AXPA17388 产品描述：

AXPA17388 is a quad bridge class AB car radio audio power amplifier designed in BCD (Bipolar, CMOS, DMOS) technology with a fully complementary P-Channel/N-Channel output structure. It has a rail to rail output voltage swing, high output current and low saturation losses, giving it an excellent distortion performance. AXPA17388 can operate down to 6V for low voltage operation to achieve 'start-stop' battery profile during engine stop enabling reduction in overall emissions.

功能描述：

▪ Multipower BCD technology with DMOS MOSFET output power stage

▪ Hi-Fi class low distortion

▪ Low output noise

▪ High immunity to RF noise injection

▪ Standby function

▪ Mute function

▪ Auto-mute at min. supply voltage detection

▪ Low external component count

▪ No external compensation

▪ No bootstrap capacitors

▪ Internally fixed gain (26dB)

▪ Capable to operate down to 6V (e.g. “start-stop”)

▪ High output power capability:

– 4 x 45W/4Ω Max.

– 4 x 25W/4Ω @ 14.4V, 1kHz, 10%

▪ Protections:

– Output short circuit to GND, to Vs, across the load

– Very inductive loads

– Overrating chip temperature with soft thermal limiter

– Load dump

– Fortuitous open GND
