Operating principle

By means of two embedded in Hall elements sensor systems IC converts signal from magnetized multi-pole coded ring (or line) into digital code of absolute position. High total conversion resolution is achieved due to coded disk with two tracks having different number of poles. IC makes it possible to use coded magnetic carriers with different number of pole pairs (up to 64) and different length of pole pair.
IC possesses embedded automated gain control (AGC) at variation of distance between magnet and IC.
To compensate for conversion error caused by inaccuracies of position sensor assembling IC has embedded unit of code position linearization.
IC settings are stored in external nonvolatile memory IC EEPROM with I2C interface (of 24LC01 type and similar ones).

IC settings (programming) is performed through SPI or OWI interfaces.

5344ХЕ025

Radiation-resistant non-contact current sensor with linear analog and digital outputs

Purpose

The microcircuit is designed to control and record electric current, both direct and alternating, with complete galvanic isolation of the measured and measuring circuits for application in the spacecraft on-board equipment. It is used to control electric motors, in particular in variable speed drives, variable frequency AC drives, converters for DC drives, overcurrent protection devices.

Operating principle

The microcircuit converts the current at the input pin into a control signal at the open collector output of the high voltage transistor. Under normal operating conditions, the operating cycle of the power transistor decreases linearly as the current on the CONTROL pin increases. It contains an N-channel field effect transistor with a control circuit, a voltage reference, a PWM regulator, a start and restart circuit, a PWM modulator error signal amplifier, and a protection circuit.
