MHGP’s YMH-HH Series is a small footprint, high performance and optically isolated gate driver module, suitable for surface mount assembly. Unlike existing isolated gate drivers, the YMH-HH Series consists of a GaAs light emitting diode, optically coupled to a silicon-based MIH™ vertical multi-junction photovoltaic cell, providing voltage isolated power to drive power semiconductor devices such as MOSFETs.
The YMH-HH Series gate driver module provides the functionality of a traditional isolated power supply, a DC-DC converter, and a gate driver IC in a single component. This integrated, completely optically isolated and powered solution simplifies gate driver design, provides better noise immunity, reduces board size and cost, and provides higher voltage isolation.

YMH-HH Series Features:

• Built-In Isolated DC/DC Power Source
• Under-Voltage Lockout Protection
• Reduces Power Supply Coupling Capacitance
• Packaging Options Include: 8 pin DFN

• MOSFET / IGBT Gate Driver
• Switch Mode Power Supply
• Inverter / Converter
• Motor Driving Module
• Variable-frequency Drive
