- Asymmetric gate voltage output configuration
- Integrated isolated DC/DC converter
- Half-bridge driver architecture
Applications
- IGBT gate driving
- MOSFET gate driving
- Industrial motor drives
- Power conversion systems
Procurement Notes
Verify the specific suffix '14N' against official Tamura documentation to confirm the exact voltage levels (+18V/-2V) and pinout compatibility. Ensure the design accommodates the absence of internal gate resistors by adding external components if required. Confirm that the module package and through-hole mounting style match the target PCB layout constraints.
Selection Notes
Select this component when asymmetric gate drive voltages are required for optimal switching performance. The magnetic coupling offers robust isolation compared to optical alternatives. Consider the lack of internal gate resistors, which allows for customizable snubber networks but requires careful PCB layout to manage parasitic inductance and EMI during high-speed switching transitions.
Part Context
This part belongs to the Tamura GDM series of gate driver units. These drivers integrate an isolated DC/DC converter and gate drive circuitry into a single module. The series is designed for high-reliability power electronics applications requiring galvanic isolation between control logic and high-power switches.
Replacement Considerations
Check for direct substitutes within the Tamura 2EG01x series, such as variants with different voltage ratings or resistor configurations. Verify pin-to-pin compatibility before substituting with other manufacturers' magnetic gate drivers.
