Iontra Closes $45 Million Series C to Deliver Launch of the Industry's First Integrated RISC-V Charge Control and Fuel Gauge Microcontroller
Iontra Inc, a Colorado-based leader in next-generation battery charging technology, announced that it has successfully completed its $45M Series C funding round with support from both current and new investors. The company has raised $120.3 Million to date. Combined with the recent DOE award of the $2.15 million ARPA-E circular grant, this solidifies Iontra’s leadership position in battery charging technology. Iontra’s funding round was led by repeat prominent energy sector investor Volta Energy Technologies, with additional support from others.
This funding will advance Iontra’s leadership position as a fabless supplier of low-cost, small-footprint battery charger microcontrollers (MCUs). With embedded Iontra charge technology, Iontra’s MCU will maximize battery performance and efficiency across a wide range of consumer and industrial products, including power tools, smartphones, and wearables.
Iontra’s MCU also includes industry standard cyber security capabilities, and advanced high-speed peripherals, allowing OEMs to unlock options for further system integration, reducing electronic Bill-of-Material (e-BOM) costs and carbon footprint.
Through Iontra’s state-of-the-art design centers and semiconductor supply chain partners, Iontra is committed to delivering a robust and reliable solution for its customers with initial samples of its custom MCU expected by mid-2025 and release to production in 2026.
