SI9976集成電路（IC）的柵極驅動器規(guī)格書PDF中文資料

SI9976屬于集成電路（IC）的柵極驅動器。由威世科技半導體制造生產(chǎn)的SI9976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 Si9976 is an integrated driver for an n-channel MOSFET half-bridge. Schmitt trigger inputs provide logic signal compatibility and hysteresis for increased noise immunity. An internal low-voltage regulator allows the device to be powered directly from a system supply of 20 to 40 volts. Both half-bridge n-channel gates are driven directly with low-impedance outputs. Addition of one external capacitor allows an internal circuit to level shift both the power supply and logic signal for the half-bridge high-side n-channel gate drive. An internal charge pump replaces leakage current lost in the high-side driver circuit to provide “static” (dc) operation in any output condition. Protection features include an undervoltage lockout, cross-conduction prevention logic, and a short circuit monitor.
