Privacy PolicyHigh-Voltage (HV) interface devices provide level translation and amplification for connecting low-voltage control circuits to HV driven load circuits. With 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 and ultrasound devices. 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. Browse the products listed below to find the right solution for your application.
HV Driver Arrays
HV driver arrays provide level translation and HV drive for multiple signals. We offer devices with different digital interfaces that range from simple digital inputs to more complex protocols:
HV Amplifier Arrays
HV amplifier arrays provide level translation and HV amplification for multiple signals in capacitive-drive applications:
High-Voltage (HV) Ultrasound Products
Our ultrasound products include high-density, multi-channel analog switches, feature-rich transmitters and oscillators with excellent close-in and floor phase noise performance. Use these devices to significantly shrink the size of your ultrasound scanner while still offering high image quality.
Product Portfolio:
Small-Signal MOSFETs and Arrays
Small-signal MOSFETs and arrays are low-current MOSFETs intended for voltage regulation, level translation, bypass and protection in systems:
- Depletion-mode N-channel MOSFETs
- Enhancement-mode N-channel MOSFETs
- Enhancement-mode P-channel MOSFETs
Complementary MOSFET (N and P channel) enhancement-mode MOSFET pairs are selected for reasonable matching and intended principally for use as drivers in ultrasound and similar applications:
Universal Relay Drivers
The HV9901 universal relay driver provides high-efficiency driving for low-voltage relays with supply voltages as high as 450V. For example, a relay with a 5V coil can be driven directly from the rectified 120 VAC or 230 VAC line.
The IC includes two HV linear regulators: the first is for providing power to internal control circuitry and the second has an adjustable output voltage and a 1-mA output current capability to support external circuitry, such as a microcontroller (MCU) control circuit.
MEMS Devices
MEMS-based laser beam steering solutions are increasingly prevalent in different markets and applications. Key applications include tracking, projection and scanning as seen in consumer AR/VR devices, automotive HUDs, lighting, LiDAR-supported navigation and systems for scanning and imaging in medical applications.
Piezoelectric Devices
Piezo-based devices for pumps and actuators are key components in industrial, consumer and medical markets. Typical piezo applications include; haptics, micro-positioning, print heads and micro-pumps.
High-Current Monitoring
A high-side current monitor IC transfers a high-side current measurement voltage to its ground-referenced output with an accurate voltage gain of one. The measurement voltage typically originates at a current sense resistor, which is located in a “high-side” circuit, such as the positive supply line.
Fault Protection
An HV fault protection switch with current foldback protects system output power supplies against overcurrent and short-circuit conditions.
