FOD8342屬于隔離器的隔離器-柵極驅(qū)動(dòng)器。由安森美半導(dǎo)體公司制造生產(chǎn)的FOD8342隔離器 - 柵極驅(qū)動(dòng)器隔離器柵極驅(qū)動(dòng)器是電源信號(hào)與外部 MOSFET 或橋接架構(gòu)電路之間的接口。技術(shù)類(lèi)型分為容性耦合、磁耦合和光耦合，提供 1、2 或 4 通道。電壓隔離范圍為 1000Vrms 至 7500Vrms，傳播延遲范圍為 30ns 至 5ms。

Description

The FOD8342 series is a 3.0 A output current gate drive

optocoupler, capable of driving medium?power IGBT/ MOSFETs. It

is ideally suited for fast?switching driving of power IGBT

and MOSFET used in motor?control inverter applications,

and high?performance power systems.

The FOD8342 series utilizes stretched body package to achieve

8 mm creepage and clearance distances (FOD8342T), and optimized

IC design to achieve reliably high?insulation voltage and high?noise

immunity.

The FOD8342 series consists of an Aluminum Gallium Arsenide

(AlGaAs) Light?Emitting Diode (LED) optically coupled

to an integrated circuit with a high?speed driver for push?pull

MOSFET output stage. The device is housed in a stretched body,

6?pin, small outline, plastic package.
