SC1405DITSTRT集成电路（IC）的栅极驱动器规格书PDF中文资料

SC1405DITSTRT属于集成电路（IC）的栅极驱动器。由升特制造生产的SC1405DITSTRT栅极驱动器栅极驱动器电源管理集成电路 (PMIC) 可用于提供隔离、放大、参考位移、自举或其他必要功能，这些功能可将来自电源转换应用中控制设备的信号连接到电源被控制通过的半导体设备（通常为 FET 或 IGBT）。任何特定设备提供的确切功能各不相同，但与它适合驱动的半导体配置相关。

Description

The SC1405D is a Dual-MOSFET Driver with an internal Overlap Protection Circuit to prevent shoot-through. Each driver is capable of driving a 3000pF load in 15ns rise/ fall time and has ULTRA-LOW propagation delay from input transition to the gate of the power FETs. Adaptive Overlap Protection circuit ensures that the synchronous FET does not turn on until the top FET source has reached a voltage low enough to prevent shoot-through. The delay between the bottom gate going low to the top gate transitioning high is externally programmable via a capacitor to minimize dead time. The bottom FET may be disabled at light loads by keeping S_MOD low to trigger asynchronous operation, thus saving the bottom FET’s gate drive current and inductor ripple current.
