SI9978DW-T1-E3集成电路（IC）的栅极驱动器规格书PDF中文资料

SI9978DW-T1-E3属于集成电路（IC）的栅极驱动器。由威世科技半导体制造生产的SI9978DW-T1-E3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 Si9978 is an integrated driver for an n-channel MOSFET H-bridge. The mode control allows operation as either a full H-bridge driver or as two independent half-bridges. The DIR/PWM input configuration allows easy implementation of either sign/magnitude or anti-phase PWM drive schemes for full H-bridges. Schmitt triggers on the 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.
