Detailed General Description Based on mixed signal CMOS technology, Melexis MLX92212LSE-AAA-000 is a Hall-effect device with very high magnetic sensitivity. Melexis MLX92212LSE-ABA-000 is a Hall-effect device with a low hysteresis covering higher magnetic fields. Both versions are allowing the use of generic magnets, weak magnets or larger air gap. The chopper-stabilized amplifier uses switched capacitor techniques to suppress the offset generally observed with Hall sensors and amplifiers. The CMOS technology makes this advanced technique possible and contributes to smaller chip size and lower current consumption than bipolar technology. The small chip size is also an important factor to minimize the effect of physical stress. This combination results in more stable magnetic characteristics and enables faster and more precise design. The operating voltage from 2.5V to 5.5V, low current consumption and large choice of operating temperature range according to “L” specification make this device suitable for automotive, industrial and consumer low voltage applications. The output signal is open-drain type. Such output allows simple connectivity with TTL or CMOS logic by using a pull-up resistor tied between a pull-up voltage and the device output 9. Latch/Switch characteristics The MLX92212-AAA exhibits magnetic latching characteristics. Typically, the device behaves as a latch with symmetric operating and release switching points (BOP=|BRP|). This means magnetic fields with equivalent strength and opposite direction drive the output high and low. Removing the magnetic field (B0) keeps the output in its previous state. This latching property defines the device as a magnetic memory. The MLX92212LSE-ABA and MLX92212LSE-ACA-000 exhibits magnetic switching characteristics. The device is south pole active: Applying a south magnetic pole greater than BOP facing the branded side of the package switches the output low. Removing the magnetic field (B0) switches the output high. The use of the opposite magnetic pole facing the branded side does not affect the output state.

For proper operation, a 10nF to 100nF bypass capacitor should be placed as close as possible to the VDD and ground pin. 2. The device could tolerate negative voltage down to -0.5 V, so if negative transients over supply line VPEAK< -32V are expected, usage of the diode D1 is recommended. Otherwise only R1 is sufficient. When selecting the resistor R1, three points are important: - the resistor has to limit IDD/IDDREV to 40mA maximum - the resistor has to withstand the power dissipated in both over voltage conditions (VR12/R1) - the resulting device supply voltage VDD has to be higher than VDD min (VDD = VCC – R1.IDD) 3. The device could tolerate positive supply voltage up to +6V (until the maximum power dissipation is not exceeded), so if positive transients over supply line with VPEAK> 6V are expected, usage a zener diode Z1 is recommended. The R1-Z1 network should be sized to limit the voltage over the device below the maximum allowed.
