DESCRIPTION

The MP8060 is a configurable dual channel full-

bridge or quad channel half-bridge used as the

output stage of a Class-D audio amplifier. Each

full-bridge can be driven independently as

stereo single ended audio amplifiers or driven

complementary in a bridge tied load (BTL)

audio amplifier configuration.

The MP8060 features a low current shutdown

mode, standby mode, input under voltage

protection, thermal shutdown and fault flag

signal output. All channels of drivers interface

with standard logic signals.

The MP8060 is available in a 32 lead QFN 5X5

package.

FEATURES

• 3.5A Peak Current Output

• Up to 600KHz Switching Frequency

• Integrated Power 0.4Ω Switches

• 30ns Switch Dead Time

• All Switches have Over-Current Protection

• Internal Under Voltage Protection

• Internal Thermal Protection

• 2.6mA Operating Current
