The ADuM4120/ADuM4120-1 are 2 A isolated, single-channel drivers that employ Analog Devices, Inc., iCoupler® technology to provide precision isolation. The ADuM4120/ADuM4120-1 provide 5 kV rms isolation in the 6-lead wide body SOIC package with increased creepage. Combining high speed CMOS and monolithic transformer technology, these isolation components provide outstanding performance characteristics, such as the combination of pulse transformers and gate drivers.

The ADuM4120/ADuM4120-1 operate with input supplies ranging from 2.5 V to 6.5 V, providing compatibility with lower voltage systems. In comparison to gate drivers employing high voltage level translation methodologies, the ADuM4120/ ADuM4120-1 offer the benefit of true, galvanic isolation between the input and the output.

Options exist for models with and without an input glitch filter. The glitch filter helps reduce the chance of noise on the input pin triggering an output.

As a result, the ADuM4120/ADuM4120-1 provide reliable control over the switching characteristics of insulated gate bipolar transistor (IGBT)/metal-oxide semiconductor field effect transistor (MOSFET) configurations over a wide range of switching voltages.

Applications

  • Switching power supplies 
  • IGBT/MOSFET gate drivers
  • Industrial inverters 
  • Gallium nitride (GaN)/silicon carbide (SiC) power devices

产品详情

评估板EVAL-ADuM4120EBZ和EVAL-ADuM4120-1EBZ支持集成米勒箝位的ADuM4120/ADuM4120-1单通道栅极驱动器。ADI公司的 iCoupler® 技术在输入信号与输出栅极驱动器之间实现隔离。EVAL- ADuM4120-1EBZ选项配有ADuM4120-1，它未集成内部输入毛刺滤波器，因此传播延迟更低。


UG-1109中的说明和器件同时适用于EVAL-ADuM4120EBZ和EVAL-ADuM4120-1EBZ。


ADuM4120/ADuM4120-1的工作电压最高可达35 V。高共模瞬变抗扰度(CMTI)和可靠的驱动强度使ADuM4120/ADuM4120-1非常适合快速开关技术。


EVAL-ADuM4120EBZ评估板有助于对该器件的传播延迟、驱动强度和输入逻辑进行测试。


有关ADuM4120/ADuM4120-1的完整信息，请参阅ADuM4120/ADuM4120-1数据手册，使用评估板时应同时参考UG-1109与数据手册。
