NCD5703集成电路（IC）的栅极驱动器规格书PDF中文资料

NCD5703属于集成电路（IC）的栅极驱动器。由安森美半导体公司制造生产的NCD5703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。

The NCx5703y are high−current, high−performance stand−alone

IGBT drivers for high power applications that include solar inverters,

motor control and uninterruptible power supplies. The devices offer a

cost−effective solution by eliminating external output buffer. Devices

protection features include accurate Under−voltage−lockout (UVLO),

desaturation protection (DESAT) and Active open−drain FAULT

output. The drivers also feature an accurate 5.0 V output. The drivers

are designed to accommodate a wide voltage range of bias supplies

including unipolar and NCx5703B even bipolar voltages.

Depending on the pin configuration the devices also include Active

Miller Clamp (NCx5703A), separate high and low (VOH and VOL)

driver outputs for system design convenience (NCx5703C)

and Enable function for driver output control by external signal

(NCx5703D).

All four available pin configuration variants have 8−pin SOIC

package.
