L5955 Voltage regulator with I²C, low voltage warning, short circuit protection and overvoltage shutdown

The L5955 is an integration of three high side drivers, six regulators and two stand-by regulators with RESET function developed to provide the power to a complete audio system.

The outputs of the IC are controlled by I²C bus and Enable pin.

The device is equipped with sequencing and slew rate controls for the st-by regulators.

技术特性
  • 2 stand-by regulators:
    • 3.3V (125mA)
    • 1.5V (300mA)
  • 6 regulators:
    • 10V (40mA)
    • 8.5V (200mA)
    • 3.3V (850mA)
    • 8/10V (1A)
    • 5/3.3/1.8V (200mA)
    • 1.8/2.5V(200mA)
  • All regulators are low dropout outputs
  • The different outputs voltage are controlled by I²C Bus.
  • Reg3 on/off controlled by enable
  • Reg1, Reg2, Reg4, Reg5, Reg6 on/off controlled by I²CBus.
  • 3 high side drivers:
    • 2A (HSD1)
    • 0.45A (HSD2 & HSD3)
  • No external charge pump capacitors are required
  • Stand-by mode controlled by EN pin for I²C Bus and Reg1, Reg2, Reg3, Reg4, Reg5, Reg6, HSD1, HSD2, HSD3
  • LVW function externally selectable
  • Individual thermal shutdown
  • Independent current limiting
  • Short circuit protection
  • Load dump protection and overvoltage shutdown
