AXPA17851产品描述
AXPA17851 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. AXPA17851 can operate down to 6V for low voltage operation to achieve 'start-stop' battery profile during engine stop enabling reduction in overall emissions.
Features
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 48W/4Ω Max.
– 4 x 28W/4Ω @ 14.4V, 1kHz, 10%
– 4 x 72W/2Ω Max.
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
