SC1205集成電路（IC）的柵極驅動器規(guī)格書PDF中文資料

SC1205屬于集成電路（IC）的柵極驅動器。由Semtech Corporation制造生產(chǎn)的SC1205柵極驅動器柵極驅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換應用中控制設備的信號連接到電源被控制通過的半導體設備（通常為 FET 或 IGBT）。任何特定設備提供的確切功能各不相同，但與它適合驅動的半導體配置相關。

Description

The SC1205 is a cost effective Dual MOSFET Driver designed for switching High and Low side Power MOSFETs. Each driver is capable of driving a 3000pF load in 20ns max rise/fall time and has a 20ns max propagation delay from input transition to the gate of the power FET’s. An internal Overlap Protection circuit prevents shoot through from Vin to GND in the main and synchronous MOSFET’s. The Adaptive Overlap Protection circuit ensures the Bottom FET does not turn on until the Top FET source has reached a voltage low enough to prevent cross-conduction.

Features

? Fast rise and fall times (15ns typical with 3000pf load)

? 3 Amp peak drive current

? 14ns max Propagation delay (BG going low)

? Adaptive Non-overlapping Gate Drives provide shoot-through protection

? Floating top drive switches up to 25V

? Under-Voltage lock-out

? Overtemperature protection

? Less than 10μA supply current when EN is low

? Low cost

Applications

? High Density sunchronous power supplies

? Motor Drives/Class-D amps/Half bridge drivers

? High frequency (to 1.2 MHz) operation allows use of small inductors and low cost caps in place of electrolytics

? High efficiency portable computers

? Battery powered applications
