STMicroelectronics L5954
The L5954 is an integration of three high side drivers and five regulators developed to provide the power for an audio system. The outputs of the IC are controlled via the I2C bus and the Enable input.FEATURES
● 5 regulators: – 10 V (350 mA) – 8.5 V (175 mA) – 5 V (350 mA) – 5 V (250 mA) – 8 V/10 V (1 A) All regulators are low dropout 3 high side drivers: – 2 A (HSD1) – 0.45 A (HSD2 and HSD3) No external charge pump capacitors are required Standby mode controlled by 3 input pins: – Enable for Reg2 and Reg3 – I2C bus for Reg1, Reg4, Reg5, Hsd1, Hsd2, Hsd3 Individual thermal shutdown Independent current limiting Short circuit protection Load dump protection and overvoltage shutdown ESD protected Device summary Order code L5954 Package Multiwatt15 Packing Tube Multiwatt15●
