| Hall Sensor KSY 14 Features * * * * * * * * * High sensitivity High operating temperature Small linearity error Low offset voltage Low TC of sensitivity and internal resistance Ultra-flat plastic miniature package Low inductive zero component Package thickness 0.7 mm Connections from one side of the package Typical applications * Current and power measurement * Magnetic field measurement * Control of brushless DC motors * Rotation and position sensing * Measurement of diaphragm * Movement for pressure sensing Dimensions in mm Type KSY 14 Marking 14 Ordering Code Q62705-K227 The KSY 14 is an ion-implanted Hall sensor generator in a mono-crystalline GaAs material, built into an extremely flat plastic package (SOH). It is outstanding for a high magnetic sensitivity and low temperature coefficients. The 0.35 x 0.35 mm2 chip is mounted onto a non-magnetic leadframe.

The by-pass circuit-breaker shall not be opened before turning on the power source, in order to avoid damage to the Hall sensor due to power peaks. Polarity of Hall voltage Semiconductor Group 3 |
