1. Functional Diagram
2. Description
The MLX90242 is a CMOS Linear Hall Effect sensor IC. It possesses active error correction circuitry which virtually eliminates the offset errors normally associated with analog Hall Effect devices. The ratiometric output voltage is proportional to the supply voltage. When using the supply voltage as a reference for an A/D converter, fluctuations of +10% in supply voltage will not affect accuracy. For a positive slope, the voltage at the output will increase as a South magnetic field is applied to the branded face of the MLX90242. Conversely, the voltage output will decrease in the presence of a North magnetic field. For a negative slope, the voltage at the output will increase as a North magnetic field is applied to the branded face of the MLX90242. Conversely, the voltage output will decrease in the presence of a South magnetic field.

Linear Hall Effect Sensor 7. Applications Information
C1 and C2 values can be trimmed to satisfied EMC requirements according to the environment (PCB, connectors,...). The output rise time is affected for large capacitor C2, depending of the couple R1;C2.

Recommended Wiring
8. Installation Comments
1.) Avoid mechanical stress on leads or package. Stress may cause VOQ shift.
A.) Avoid bending leads at the package interface. B.) Support the leads by clamping, when bending. C.) Avoid gluing device to another material.
C1 = 10nF 1

R1 = 10 k C2 = 2.5nF
V OUT
This may cause temperature-related stress. 2.) CMOS products are static sensitive devices, please observe ESD precautions. 3.) Observe temperature limits during soldering
9. Reliability Information
Melexis devices are classified and qualified regarding suitability for infrared, vapor phase and wave soldering with usual (63/37 SnPb-) solder (melting point at 183degC). The following test methods are applied: IPC/JEDEC J-STD -020A (issue April 1999) Moisture/Reflow Sensitivity Classification For Nonhermetic Solid State Surface Mount Devices CECC00802 (issue 1994) Standard Method For The Specification of Surface Mounting Components (SMDs) of Assessed Quality MIL 883 Method 2003 / JEDE C-STD-22 Test Method B102 Solderability For all soldering technologies deviating from above mentioned standard conditions (regarding peak temperature, temperature gradient, temperature profile etc) additional classification and qualification tests have to be agreed upon with Melexis. For process using through hole components, a temperature profile of 235 Deg.C during 30 seconds maximum is tolerated.
The application of Wave Soldering for SMD's is allowed only after consulting Melexis regarding assurance of adhesive strength between device and board. Please contact MLX for Ua part used as SMD device.
