What iSentek does
iSentek is a fabless semiconductor company founded in June 2011 and headquartered in New Taipei City, Taiwan, that designs and sells magnetic sensor integrated circuits (ICs) for consumer, industrial, automotive, medical, IoT, and UAV/drone applications. The company is publicly listed on the Taiwan Stock Exchange (TWSE: 6978) and operates regional sales offices in Fremont (CA), Shenzhen, and Beijing. With 11-50 employees and 88 patents covering sensing technologies and ASIC designs, iSentek is positioned as a specialist with 25+ years of accumulated magnetic-sensing and semiconductor expertise.
iSentek develops products across four core magnetic sensing platforms — Tunnel Magnetoresistance (TMR), Hall Effect, Anisotropic Magnetoresistance (AMR), and Fluxgate — selecting the optimal sensing method based on system-level requirements rather than technology constraints. The company co-designs analog and digital ASICs alongside the sensing elements in-house, which optimizes the signal chain and reduces noise at the system level. Notable product families include nanopower TMR switches (IST8505 and IST8505H2 with standby currents as low as 10-20nA at 1Hz), 3D AMR magnetometers/eCompasses (IST8305, IST8308, IST8310) for consumer, industrial, and UAV use cases, and the IST8306 high-precision magnetometer recognized as EET 'Best Sensor of the Year' in 2023. Supporting offerings include evaluation boards and simulation tools (Magnetic Design Simulator, Current Sensor Simulator, Leakage Current Design Tool).
Revenue is generated primarily through hardware sales of magnetic sensor ICs through a network of authorized distributors, with Digikey listed as a sample purchase channel. The company operates a hybrid go-to-market combining channel partner sales with enterprise field sales through regional offices and a gated customer portal requiring NDA registration for advanced datasheets and FAE support. Pricing is not publicly disclosed. Tier-1 design wins include mass production of IST8310 with the world's leading drone supplier, with additional design-ins among Chinese smartphone, smart watch, industrial, and drone manufacturers. The company holds ISO 9001 certification and maintains RoHS, REACH, and Conflict Minerals compliance declarations.
