LT3845集成電路（IC）的PMIC-穩(wěn)壓器-DCDC開關(guān)式控制器規(guī)格書PDF中文資料

LT3845屬于集成電路（IC）的PMIC-穩(wěn)壓器-DCDC開關(guān)式控制器。由亞德諾半導體技術(shù)有限公司制造生產(chǎn)的LT3845DC-DC 開關(guān)控制器PMIC（電源管理集成電路）DC 到 DC 開關(guān)式控制器是用于高效率電路的穩(wěn)壓 IC，其配置為生成高于（突升或步升）或低于（突降或步降）輸入電源的輸出電源電壓。其他拓撲結(jié)構(gòu)可能包括：降壓-升壓、反激、正激、Cuk、SEPIC、全橋、半橋和推挽式。這些器件不同于需要最小電壓并“燒盡”多余電壓的線性穩(wěn)壓器。

DESCRIPTION

The LT?4356-3 surge stopper protects loads from high voltage transients. It regulates the output during an overvoltage event, such as load dump in automobiles, by controlling the gate of an external N-channel MOSFET.

FEATURES

■ Stops High Voltage Surges

■ Adjustable Output Clamp Voltage

■ Overcurrent Protection

■ Wide Operation Range: 4V to 80V

■ Reverse Input Protection to –60V

■ Low 7μA Shutdown Current

■ Adjustable Latchoff Fault Timer

■ Controls N-channel MOSFET

■ Shutdown Pin Withstands –60V to 100V

■ Fault Output Indication

■ Auxiliary Amplifier for Level Detection Comparator or

Linear Regulator Controller

■ Available in 12-Pin 4mm × 3mm DFN,

10-Pin MSOP, and 16-Pin SO Packages

APPLICATIONS

■ Automotive/Avionic Surge Protection

■ Hot Swap/Live Insertion

■ High Side Switch for Battery Powered Systems
