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 × 0.35 mm2 chip is
mounted onto a non-magnetic leadframe.

Connection of a Hall sensor with a power source
Since the voltage on the component must not exceed 10 V, the connection to the
constant current supply should only be done via a short circuit by-pass. 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.
