Entry-level hall sensor has enhanced diagnosis capabilities

October 07, 2016 // By Christoph Hammerschmidt
The HAL 1860 from Micronas is a cost-effective linear hall-effect sensor with a ratiometric analog output targeting small stroke rotary and distance measurements for automotive and industrial applications.

Programmable output clamping levels make it possible to detect error conditions like under- and overvoltage, under- and overflow of the signal path and overcurrent. The single-pin programming interface also enables simultaneous programming of multiple sensors through the output pins. The most central sensor characteristics and parameters such as magnetic field range, sensitivity, offset and temperature coefficients can be stored in a non-volatile memory.

Micronas highlights the sensor’s small footprint and package size as well as its specific protection features which make the HAL 1860 ideal for applications with restricted space and harsh environments. The signal output can be monitored to ensure signal integrity; the chip’s diagnostics capabilities and clamping functions are typically found in more expensive products, explained product marketing manager Matthieu Rezé. Customers also can increase their productivity by leveraging the potential of the programming interface to optimize the sensor performance at the end of their production line.

These features make the HAL 1860 suited for system solutions to measure small angles (less than 90 degrees) as well as linear motion of a few millimeters in demanding applications. Examples are gear position detection sensors in dual-clutch automatic transmission or steering torque sensors for industrial and recreational vehicles. 

The device is qualified according to AEC-Q100 and comes in an industry standard 3-pin TO92-UA, It is available in two lead forming configurations: an inline version with 1.27 mm pin-to-pin spacing or alternatively a spread version with 2.54 mm pin-to-pin spacing, better suited for welding process.

The device will be shown at the electronica trade fair in Munich (November 8 to 11, hall 11, booth 219).
