New CMOS tech based Linear Hall Sensors from Micronas for automobile apps

The HAL 1821/1822/1823 are new members of the linear Hall-effect sensor family HAL 182x from Micronas, offers high reliability for use in automobiles, domestic and industrial applications.

The new Hall Sensors are designed for use in automobiles, with high EMC performance and with internal overvoltage and reverse voltage protection at the power supply pins.

A Hall-effect sensor detects the presence of a magnet without requiring actual physical contact. Thus, it can be used to sense movement and rotation without requiring contact with the moving object. Other parameters like pressure, force or torque can be sensed by noting the slight movements of a magnet caused by changes of the applied parameter.

Micronas' says that its CMOS technology based Hall-effect sensors allow integration of the Hall-effect sensing element with electronic devices such as amplifiers, logic circuits, and volatile and non-volatile memories.

"The linear Hall sensors HAL 1821, HAL 1822 and HAL 1823 are available with different levels of sensitivity to match application requirements. In contrast to the HAL 1820, the programming functionality has been dropped with the new types in order to achieve the better price-performance ratio. The sensors can be used to determine position, direction of motion, fluid level and for current measurements. They can also be used to replace classic potentiometers", says Peter Zimmermann, Director Marketing at Micronas.

Operating temperature range (TJ): -40 °C to +170 °C

Package: Small leaded package TO92UA and small SMD package SOT89B
Price: Depending on type, the sensors are on offer at a price ranges from EUR 0.65 and 0.75 for 100k pieces
Availability: Samples in the TO92UA package are available from 2nd quarter of 2010
