CDMOS Linear Integrated Circuit Silicon Monolithic

TCB501HQ

Maximum Power 49 W BTL × 4ch Audio Power Amp IC

1. Description

The TCB501HQ is a power IC with built-in four-channel BTL

amplifier developed for car audio application. The maximum

output power POUT is 49 W using a pure complementary P-ch

and N-ch DMOS output stage.

In addition, a standby switch, a mute function, output offset

voltage detector, high-side switch and various protection features

are included.

Weight: 7.7g (typ.)

2. Applications

Power Amp IC developed for car audio applications.

3. Features

• High output power, low distortion, and low noise property (for details, refer to the Table 1 Typical

Characteristics).

• Built-in high-side switches. (Pin 25)

• Built-in output offset detection for full time (Pin 1)
