What ITM Semiconductor does

ITM Semiconductor Co., Ltd. (KOSDAQ: 084850) is a South Korea-based semiconductor and battery protection circuit manufacturer founded in 2000 and headquartered in Cheongju, Chungcheongbuk-do. The company employs approximately 2,500 people across two Korean facilities, four Vietnam factories, a US sales office in San Jose, a China sales office in Shenzhen, and a newly established Indonesia plant (July 2025). ITM sells primarily to global mobile phone manufacturers, electronics OEMs, tobacco companies (most notably KT&G for the Lil Hybrid heated tobacco device series), and is expanding into automotive BMS and energy storage applications.

The company's product portfolio is anchored on its proprietary POC (Protection One Chip, launched 2005) and PMP (Protection Module Package, launched 2012) technologies, which integrate protection ICs and MOSFETs into single packages for secondary battery protection. The full stack extends to battery packs (polymer and square form factors for wearables, mobile devices, and power tools), Master/Slave BMS for EVs and large-scale storage, MEMS and optical sensors (proximity, illumination, heart rate, pressure, acceleration, dust, temperature, humidity, infrared), and dual-standard (WPC and AirFuel Alliance) wireless charging ICs. ITM claims a Global No.1 position in secondary battery protection circuits based on its first-mover integrated architectures and a manufacturing footprint few niche competitors can match.

ITM generates revenue through direct B2B enterprise sales of hardware (semiconductor components, battery packs, BMS modules, sensors, and finished heated tobacco devices). Pricing is not publicly disclosed at SKU level; the heated tobacco segment alone generated 117.2B KRW (~$100M) in the most recent disclosed year with 22% YoY growth. Following a peak revenue of ~503B KRW in 2022, the company announced a February 2025 portfolio restructuring to exit loss-making segments and refocus on e-cigarettes, protection circuits, and sensors, while pursuing mid-to-long-term diversification into defense, energy storage, robotics, and AI (the latter via a March 2026 MOU with AIMFuture).
