    Microchip's High-Voltage Interface Solutions

    High-Voltage (HV) interface devices provide level translation and amplification for connecting low-voltage control circuits to high-voltage driven load circuits. Excellent options for use in MEMS- or piezo-based devices with varying drive requirements, our rich portfolio of HV devices ranges from simple MOSFETs to complex multi-channel HV driver ICs. We also offer digital interfaces that offer simple digital inputs to more complex protocols, such as SPI and I2C. Our more complex HV IC products enable serial-to-parallel conversion functionality, support voltages up to 300V and offer up to 128  output channels. Look through the products listed below to find the right solution f or your application.

    MOSFETs - Interface

    Low-current MOSFETs intended for voltage regulation, level translation, bypass and protection in systems:

    Complementary MOSFET (N and P Channel) Enhancement Mode MOSFET pairs selected for reasonable matching, intended principally for use as drivers in ultrasound and similar applications:

    HV Driver Arrays

    Provide level translation and high-voltage drive for multiple signals; different digital interfaces include simple digital inputs to more complex protocols available:

    HV Amplifier Arrays

    Provide level translation and high-voltage amplification for multiple signals in capacitive-drive applications:
