HAL1000UT-A傳感器變送器的磁性傳感器-開(kāi)關(guān)（固態(tài)）規(guī)格書(shū)PDF中文資料

Introduction The HAL 1000 is a programmable Hall switch. The major sensor characteristics, the two switching points BON and BOFF, are programmable for the application. The sensor can be programmed to be unipolar or latching, sensitive to the magnetic north pole or sensitive to the south pole, with normal or with an electrically inverted output signal. Several examples are shown in Fig. 2–4 through Fig. 2–7.

Features

– high-precision Hall switch with programmable switching points and switching behavior

– switching points programmable from ?150 mT up to 150 mT in steps of 0.5 of the magnetic field range

– multiple programmable magnetic characteristics in a non-volatile memory (EEPROM) with redundancy and lock function

– temperature characteristics are programmable for matching all common magnetic materials

– programming through a modulation of the supply voltage

– to enable programming of an individual sensor amongst several sensors parallel to the same supply voltage, each sensor can be selected via its output pin

– operates from ?40 °C up to 150 °C ambient temperature

– operates from 4.5 V up to 5.5 V supply voltage in specification and functions up to 8.5 V

– operates with static magnetic fields and dynamic magnetic fields up to 2 kHz

– magnetic characteristics extremely robust against mechanical stress effects

– overvoltage and reverse-voltage protection at all pins

– short-circuit protected push-pull output

– EMC and ESD optimized design
