Part Number : L5955
Function : Multiple multifunction voltage regulator for car radio
Package : Flexiwatt27 Type
Manufacturers : STMicroelectronics
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.
■ 2 stand-by regulators:
■ 6 regulators:
■ 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 I2C Bus.
■ 3 high side drivers:
0.45A (HSD2 & HSD3)
■ No external charge pump capacitors are required
■ Stand-by mode controlled by EN pin for I2CBus 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
