Power amplifier for automotive audio systems is resistant to power surges

Toshiba Electronics Europe has launched a new 4-channel power amplifier for automotive audio applications that is highly resistant to the power surges typically found within vehicle electronics.

Building on Toshiba’s proven development capabilities in ICs for automotive audio, the highly reliable 4-channel TCB503HQ delivers 50W of output power per channel into a 4Ω load. The highly featured device includes built-in mute and standby functions as well as protection functions such as offset detection and short circuit detection as well as overvoltage and over temperature.

The TCB503HQ also includes a built-in filter to improve resistance to extraneous high-frequency noise that may be present in the vehicle. This filter also prevents the generation of abnormal noises from the amplifier due to high-frequency noise from onboard electronics, such as motors, or other devices such as smartphones.

It also supports 6V operations, making it suitable for vehicles equipped with idling reduction systems, which have become popular in recent years. This feature suppresses the ‘popping’ sounds that can occur when the supply voltage fluctuates.

The clip detection signal can be used to control the volume and tone control circuits, thereby improving the sound quality of the audio system.

Sample shipments start today with mass production scheduled to begin in the first quarter of 2019.

GaN’s Ground-Floor Opportunity
The electronics industry has a major role to play in helping to save energy, by enabling better equipment and new ways of working and living that that are more efficient and environmentally friendly. Maintaining the pace of technological progress is key, but improvements become both smaller and harder to achieve as each technology matures. We can see this trend in the development of power semiconductors, as device designers seek more complex and expensive ways to reduce switching energy and RDS(ON) against silicon’s natural limitations.
