45-W class 4-channel Automotive Audio Power Amplifier IC with using a new CD-0.13 process: TCB001HQ

TCB001HQ image

The engine with an idle reduction system is shut down when the vehicle stops, causing the battery voltage to drop instantaneously. The new power amplifier reduces the minimum operation voltage from 8 V to 6 V, and thereby realizes stable amplifier operation, making it possible to prevent sound loss and noise in car audio.

"TCB001HQ" improves noise tolerance with a newly developed filter circuit, and minimizes the influence of cell phone radio waves on the sound. Reinforced protection circuits realize high reliability.

  • Maximum Output Power:
    45W × 4ch (VCC=15.2V, RL=4Ω,  MAXPOWER)
  • Output Noise Voltage: 45µVrms (BW=20Hz to 20kHz)
  • Operating Supply Voltage Range: 6 to 18 V (4Ω)
  • Package: HZIP25-P-1.00F

Embedded Functions and Features

  • High output power and low distortion
  • Built-in mute and standby functions
  • Optional functions (output DC offset detection,
    output short detection, and overvoltage detection)
  • Support start-stop compatibility (prevention of instantaneous
    voltage drop on entry to an idle reduction mode)
  • Support excellent GSM noise immunity
  • Variety of protection circuits (thermal shutdown, overvoltage, short-to-VCC, short-to-GND and short-to-load)
