KSY 44

The KSY 44 is a MOVPE¹⁾Hall sensor 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 mm²chip 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.
