L5955屬于集成電路（IC）的特殊用途穩(wěn)壓器。由意法半導(dǎo)體集團(tuán)制造生產(chǎn)的L5955特殊用途穩(wěn)壓器該系列產(chǎn)品用于電源控制、某種形式的轉(zhuǎn)換，適用于特定的復(fù)雜應(yīng)用。因此，各種產(chǎn)品特性集差異較大，包括空燃比傳感器接口、汽車交流發(fā)電機(jī)電壓調(diào)節(jié)、DDR 端接、液體透鏡控制、摩托車轉(zhuǎn)向信號(hào)控制、熱電 (peltier) 冷卻器控制、壓電觸覺控制、閥門控制、小型發(fā)動(dòng)機(jī)管理等。

Description

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.

Features

■ 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
