L6390D屬于集成電路（IC）的柵極驅(qū)動器。由意法半導(dǎo)體集團制造生產(chǎn)的L6390D柵極驅(qū)動器柵極驅(qū)動器電源管理集成電路 (PMIC) 可用于提供隔離、放大、參考位移、自舉或其他必要功能，這些功能可將來自電源轉(zhuǎn)換應(yīng)用中控制設(shè)備的信號連接到電源被控制通過的半導(dǎo)體設(shè)備（通常為 FET 或 IGBT）。任何特定設(shè)備提供的確切功能各不相同，但與它適合驅(qū)動的半導(dǎo)體配置相關(guān)。

描述 Description

The L6390 is a high-voltage device manufactured with the BCD OFF-LINE technology. It is a monolithic half-bridge gate driver for N-channel Power MOSFET or IGBT.

The high side (floating) section is designed to stand a voltage rail up to 600 V. The logic inputs are CMOS/TTL compatible down to 3.3 V for easy interfacing microcontroller/DSP.

The IC embeds an operational amplifier suitable for advanced current sensing in applications such as field oriented motor control.

An integrated comparator is available for protections against over-current, over-temperature, etc.
