Innoscience announces new GaN driver IC designed to drive LV, MV and HV e-mode GaN HEMTs

Innoscience Technology has introduced the INS1001DE GaN driver IC, specifically engineered to power single-channel GaN HEMTs in low-side, high-side, or secondary-side SR applications.

According to Innoscience, the INS1001DE is an ideal choice for maximizing the efficiency of e-mode GaN HEMTs, especially when used with Innoscience’s e-mode InnoGaN. The INS1001DE is highly ideal for high power, high frequency, and resilient power GaN applications because to its strong driving performance, rapid propagation delay, input noise deglitching, and built-in protective features such as UVLO, OVP, and OTP.

The new gate driver features both non-inverting and inverting PWM inputs, allowing for versatile operation with a controller, opto-coupler, and digital isolator. The presence of Independent Pull-up and Pull-down outputs allows for precise regulation of the pace at which a device is turned on and off. The voltage of the driver can be adjusted by the user to meet various gate requirements by utilizing an external resistor divider. A built-in 5V low-dropout regulator (LDO) is provided to power digital isolators or other circuits in high-side applications.

The INS1001DE is a component that operates within a voltage range of 6V to 20V. It has a pull-up resistance of 1.3Ω and a pull-down resistance of 0.5Ω. It is packaged in a thermally enhanced DFN3x3-10L package. The applications encompass switch-mode power supply, AC/DC and DC/DC converters, Boost, Flyback, Forward, Half-Bridge and Full-Bridge converters, synchronous rectification circuits, solar inverters, motor control, and UPS.

The main features offered by the INS1001DE single-channel GaN driver are the following:

Maurizio Di Paolo Emilio holds a Ph. D. in Physics and is a Telecommunications Engineer. He has worked on various international projects in the field of gravitational waves research, designing a thermal compensation system (TCS) and data acquisition and control systems, and on others about x-ray microbeams in collaboration with Columbia University, high voltage systems and space technologies for communications and motor control with ESA/INFN. TCS has been applied to the Virgo and LIGO experiments, which detected gravitational waves for the first time and earned the Nobel Prize in 2017. Since 2007, he has been a reviewer for scientific publications for academics such as Microelectronics Journal and IEEE journals. Moreover, he has collaborated with different electronic industry companies and several Italian and English blogs and magazines, such as Electronics World, Elektor, Mouser, Automazione Industriale, Electronic Design, All About Circuits, Fare Elettronica, Elettronica Oggi, and PCB Magazine, as a technical writer/editor, specializing in several topics of electronics and technology. From 2015 to 2018, he was the editor-in-chief of Firmware and Elettronica Open Source, which are technical blogs and magazines for the electronics industry. He participated in many conferences as a speaker of keynotes for different topics such as x-ray, space technologies, and power supplies. Maurizio enjoys writing and telling stories about Power Electronics, Wide Bandgap Semiconductors, Automotive, IoT, Embedded, Energy, and Quantum Computing. Maurizio has been an AspenCore content editor since 2019. He is currently editor-in-chief of Power Electronics News and EEWeb and a correspondent for EE Times. He is the host of PowerUP, a podcast about power electronics, and the promoter and organizer of the PowerUP Virtual Conference, a summit where each year great speakers talk about the power electronics design trends. Moreover, he has contributed to a number of technical and scientific articles as well as a couple of Springer books on energy harvesting and data acquisition and control systems.
