L5955
Overview
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.
- 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 Device summary Order code L5955 Package Flexiwatt27 Packing Tube * * *
