9. Detailed General Description
Based on mixed signal CMOS technology, Melexis US5782 is a Hall-effect device with medium magnetic sensitivity. Its sensitivity
enables high accuracy in position sensing by the use of small air gap.
The chopper-stabilized amplifier uses switched capacitor technique 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 wide operating voltage from 3.5V to 24V, wide operating temperature according “L” specification and low current
consumption make this device especially suitable for automotive and solid state switch 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.
10. Unique Features
The US5782 exhibits unipolar magnetic switching characteristics. Therefore, it operates only with one magnetic pole.
Output level
The US5782 device is south pole active:
Applying a south magnetic pole greater than BOP facing the
branded side of the package switches the output low.
OUT switches to High
OUT switches to Low
OUT = High
Removing the magnetic field (B0) switches the output high.
The use of the opposite magnetic pole facing the branded side
does not affect the output state.
OUT = Low

BRP

Flux density
Unipolar switch characteristic
A magnetic hysteresis BHYST keeps BOP and BRP separated by a minimal value. This hysteresis prevents output oscillation near the
switching point.

13. Application Comments
For proper operation, a 100nF bypass capacitor should be placed as close as possible to the device between the VDD and ground
pin.
For reverse voltage protection, it is recommended to connect a resistor or a diode in series with the V DD pin.
When using a resistor, three points are important:
- the resistor has to limit the reverse current to 50mA maximum (VCC / R1 50mA)
- the resulting device supply voltage VDD has to be higher than VDD min (VDD = VCC – R1.IDD)
2
- the resistor has to withstand the power dissipated in reverse voltage condition (P D = VCC / R1)
When using a diode, a reverse current cannot flow and the voltage drop is almost constant (0.7V).
Therefore, a 100/0.25W resistor for 5V application and a diode for higher supply voltage are recommended. Both solutions
provide the required reverse voltage protection.
When a weak power supply is used or when the device is intended to be used in noisy environment, it is recommended that
figure 13.3 from the Application Information section is used.
The low-pass filter formed by R1 and C1 and the zener diode Z1 bypass the disturbances or voltage spikes occurring on the device
supply voltage VDD. The diode D1 provides additional reverse voltage protection.
