iC-Haus intros 12bit universal magnetic position encoder

iC-Haus has announced the iC-MHL200, which according to the company, is an integrated system solution for linear and angular magnetic encoder applications. The chip is housed in a TSSOP20 package that includes a linear Hall sensor array, which is adapted to the targets' magnetic pole pitch of 2mm.

The internal signal amplification control compensates for deviations of the sensor signals due to temperature and working gap variations. Incremental (AB quadrature and Z index, 12bit) and commutating signals (UVW) are provided at the RS422 compatible line driver outputs.

An external reference signal can be used to gate the internal index Z signal to provide an absolute zero pulse. The linear resolution is configurable up to 4096 steps per each magnetic signal period of 4mm, which corresponds to an incremental linear displacement of less than 1?.

At the fastest incremental output frequency of 8MHz, linear movements of up to 8m/s can be tracked with full 12bit resolution. The UVW commutation signals are available for two- and four pole linear motor configuration.

iC-MHL200 is typically used in industrial, automotive, and medical applications such as position control and acquisition, linear/rotary speed control, motor control, and as substitute for optical incremental encoders.

A synchronous serial SSI/bidirectional BiSS-C interface provides additional serial data output. Using BiSS-C allows for setting device configuration. These settings can be permanently stored in an OTP-ROM.

iC-MHL200 operates from a supply voltage of 5V (±10 per cent) within an operating temperature range of -40°C to 125°C.
