Description

This sensor family consists of different two-wire Hall switches produced in CMOS technology. All sensors change the current consumption depending on the external magnetic field and require only two wires between sensor and evaluation circuit. The sensors of this family differ in the magnetic switching behavior and switching points.

Specifications and Features

• Current output for two-wire applications
• Low current consumption: 5 mA...6.9 mA
• High current consumption: 12 mA...17 mA
• Junction temperature range from −40 °C up to 140 °C.
• Operates from 3.75 V to 24 V supply voltage
• Operates with static magnetic fields and dynamic magnetic fields up to 10 kHz
• Switching offset compensation at typically 145 kHz
• Overvoltage and reverse-voltage protection
• Magnetic characteristics are robust against mechanical stress effects
• Constant magnetic switching points over a wide supply voltage range
• The decrease of magnetic flux density caused by rising temperature in the sensor system is compensated by a built-in negative temperature coefficient of the magnetic characteristics
• Ideal sensor for applications in extreme automotive and industrial environments
• EMC corresponding to ISO 7637
