Every switch needs a gate driver. Gate Driver Products are the interface between control signals (from a digital or analog controller) and power switches (IGBTs, MOSFETs, SiC MOSFETs, and GaN HEMTs). Their additional functions can include level shifting, isolation, fault sensing and signal conditioning. We offer a broad selection tailored for a variety of power switches, topologies and applications. ON Semiconductor’s diverse portfolio of gate drivers contains the right solution for a range of systems including Automotive, Industrial, Cloud and Telecom applications.

SECO−GDBB−EVB is a baseboard conceived for use as a plug and play environment for testing various types of gate drivers. The board enables to feed the drivers with the same control signal under same conditions and compare their capabilities. It is set up to accommodate up to six driver boards (daughter boards) designed to test gate drivers functions and features (all driver boards are pin compatible with baseboard).

Galvanic isolation is provided in the gate drive PWM logic signal from the controller using a part such an optocoupler or digital isolator. Then the isolated PWM signal is fed to the gate driver to turn on and off the switch.
Characteristics:
A junction isolated gate driver does not provide true galvanic isolation. A semiconductor junction in the driver allows a floating well to rise and fall with the switch node, and therefore be able to control the high side gate.
Characteristics:
Galvanic isolation allows power or signal transfer between two electrical circuits without a shared current flow (circuits separately grounded). This can increase the reliability and safety of power systems and protects sensitive circuits from transients.
