Linear Hall sensor from Micronas for automotive, domestic and industrial apps

Micronas' HAL 1820 is a new family of value-optimized linear Hall sensors with integrated EEPROM programmability for use in automotive, domestic and industrial applications.

The HAL 1820 meets quality criteria of an automotive component, has better EMC capability and features internal overvoltage and reverse voltage protection at the power supply terminal.

"The electrical characteristics of the sensor such as field strength, sensitivity, offset and temperature coefficient are stored in an internal EEPROM. Programming is made by modulating the supply voltage, which means there is no need for an additional connection pin", says Peter Zimmermann, Director Marketing at Micronas.

The programmability function allows the two-point calibration by adjusting the ratiometric output signal directly to the input signal (e.g. generated by angle, distance or current). Each sensor can be individually adjusted during the production process. With this calibration method, the tolerance values of the sensor, of the magnet and the mechanical positioning can be compensated in the final assembly. This sensor is suggested for applications calling for mechanical adjustment or laser trimming for calibrating the system.

Programming board is available for the development of applications using the HAL 1820.
