The device provides up to 22 W into 4 Ω at less than 10% THD+N from a 14.
4-Vdc automotive battery.
The wide operating voltage range and excellent efficiency make the device ideal for startstop support or running from a backup battery when required.
The integrated load-dump protection reduces external voltage clamp cost and size, and the onboard load diagnostics report the status of the speaker through I2C.
