Current-Feedback 4ch Power Amplifier IC for Car Audio with Built-In Full-Time Offset Detection: TCB502HQ 更多

This photo shows the TCB502HQ .

Toshiba Corporation’s Storage & Electronic Devices Solutions Company today announced the launch of the TCB502HQ, a 4-channel power amplifier IC that detects output offset voltage that is a factor in speaker burnout. Mass production is scheduled to start in December 2016.
To respond to growing demand for superior sound quality of car audio, the new IC integrates a current-feedback system of the type adopted in high-end hi-fi audio. This prevents sound quality degradation at wide bandwidths and offers consistent sound quality, considering overtone of musical instruments or human voice.
The new IC also integrates a newly developed, full-time offset detection circuit. It detects offsets generated at the output stage even during playback and contributes to reduction of field failures, thus helping ensure high reliability.

  • Maximum Output Power:
    49W×4ch(VCC=15.2V, RL=4Ω, MAXPOWER)
  • Output Noise Voltage: 33 µV (BW=A-weigh)
  • Operating Supply Voltage: 6 ~18 V (4Ω), 6 ~16 V (2Ω)
  • Package: HZIP25-P-1.00F
  • Embedded Functions and Features:
    • High output and low distortion
    • Built-in mute and standby functions, offset detection, and short-circuit detection
    • 6 V operation (engine idling reduction)
    • A range of protection circuits (thermal, overvoltage, output to VCC, output to GND, output to output)

45-W class 4-channel power amplifier IC with using a new CD-0.13 process: TCB001HQ 更多

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: 55 µV (BW=DIN_AUDIO)
  • 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)

"TCB501HQ" integrates a newly developed, full-time offset detection circuit. Conventional offset detection during sound reproduction is difficult.It detects output DC offset voltage caused by leakage from the input capacitor and other sources, even during sound reproduction, and prevents speaker burnout.
It also integrates a current-feedback system of the type adopted in high-end hi-fi audio. This prevents sound quality degradation at wide bandwidths and offers consistent sound quality.  

  • Maximum Output Power:
    49W × 4ch (VCC=15.2V, RL=4Ω, MAXPOWER)
  • Output Noise Voltage: 33 µV (BW=A-weigh)
  • Operating Supply Voltage Range:
    6 to 18 V (4Ω), 6 to 16V (2Ω)
  • Package: HZIP25-P-1.00F
  • Embedded Functions and Features
    • High output power and low distortion
    • Built in mute and standby functions, offset detection, and high side switch driver
    • 6V operations (Engine idling reduction capability)
    • Variety of protection circuits (thermal, overvoltage, shorted to VCC, shorted to GND and shorted load)
