 TCB001HQ

The four-channel power amp IC, TCB001HQ, delivers improved noise reduction and limits the effect of interference caused by in-car mobile phone use.

Stopped vehicles fitted with engine idling reduction technology can suffer significant drops in battery output voltage, which can adversely affect the sound quality and clarity of in-car entertainment systems. By reducing the minimum operating voltage from 8V to 6V, this power amplifier offers more stable operation, prevents loss of sound and reduces noise disturbance. With mobile phone interference protection, the TCB001HQ improves the in-car listening experience.

The TCB001HQ also offers a newly developed filter circuit and reinforced protection circuits, including thermal over-voltage, output to VCC, output to GND and output-to-output protection to ensure increased reliability. Built-in mute and standby functions help to maintain battery charge.
