TC4427EMF

The TC4427EMF is a high performance dual MOSFET driver meant to be used with multiple high current gate drive requirements. It contains two independent power MOSFET drivers inside, each with a source current capacity up to 500mA. The TC4427EMF is a wide operating voltage range device, capable of operating from 2.7V to 18V. These features make the TC4427EMF perfect for a variety of applications, from power switching to automotive applications.

The main purpose of the TC4427EMF is to increase the speed and reduce the power dissipation of power MOSFETs. It does this by typically consuming only 3mA of device input current and producing a 16mA output current. This is accomplished by creating a channel from the ground pin to the MOSFET’s drain terminal, creating an effective charge and discharge current path. The TC4427EMF is also capable of creating a larger current swing by combining the two drivers. This allows for rapid switching and reduced power consumption, along with improved efficiency and reliability.
