STMicroelectronics Amplificateurs de puissance série TDA.

Les amplificateurs de puissance série TDA de STMicroelectronics sont de nouveaux amplificateurs de radio automobile à deux ou quatre ponts. Ils sont conçus avec la technologie BCD, afin d'inclure une vaste gamme de caractéristiques novatrices, dans un appareil très compact et flexible. Ils sont dotés d'un ensemble de diagnostic complet, communiquant le statut de chaque haut-parleur par le bus I2C.

Caractéristiques

  • Multipower BCD technology
  • MOSFET output power stage
  • DMOS power output

  • High output power capability 4Wx25W/4Ω out power @ 14.4V, 1kHz, 10% THD, 4x45W max power
  • 2Ω driving capability (64W max power)
  • Full I2C bus driving
    • Standby
    • Independent front/rear soft play/mute
  • I2C bus digital diagnostics (including DC and AC load detection)
  • High efficiency enable/disable
  • Flexible fault detection through integrated diagnostic
  • DC offset detection
  • Four independent short circuit protection
  • Clipping detector pin with selectable threshold (2%/10%)
  • Standby/mute pin
  • Linear thermal shutdown with multiple thermal warning
  • ESD protection
  • Very robust against misconnections
  • Improved SVR suppression during battery transients
  • Capable to operate down to 6V (e.g. "Start-stop")
