Low-Power, Ultra-Accurate 6 DoF IMU

HKE21105  (MAX21105 now manufactured by Hanking)*

The HKE21105 is a monolithic, 3-axis gyroscope plus 3-axis accelerometer ultra-accurate Inertial Measurement Unit (IMU). The HKE21105 is one of the industry’s most accurate IMUs inertial measurement unit, available in a 3mm x 3mm x 0.83mm package and capable of working with a supply voltage as low as 1.71V. HKE21105 is available in a 16-lead plastic land grid array (LGA) package and can operate within a temperature range of -40°C to +85°C.

MAX 21105 * – Data Sheet


*Hanking Electronics (Liaoning) Co., Ltd. acquired the Maxim Integrated MEMS business, product line and associated patents in 2016.   As part of Maxim Integrated’s MEMS portfolio, Maxim had acquired Sensor Dynamics

SensorDynamics held numerous original patents for MEMS sensor technology. It had devoted
over 800 man‐years of research and development to the high‐growth fields of MEMS sensors
and associated low power interface and wireless connectivity solutions. Consequently, this
acquisition enabled Maxim, and now Hanking, to accelerate expansion in markets where it already has a strong presence including the automotive and high‐end consumer.

Hanking now manufactures the MEMS inertial products in China at its HQ in Fushun.
