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, “L” and “E” operating temperature range and low current consumption make this device especially suitable for automotive 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. Unique Features The US5881 exhibits unipolar magnetic switching characteristics. Therefore, it opera tes only with one magnetic pole. Output level The UA package is south pole active: Applying a south magnetic pole greater than B OP facing the branded side of the package switches the output low. OUT switches to High OUT switches to Low OUT = High The SE package is north pole active: Applying a north magnetic pole greater than B OP facing the branded side of the package switches the output low. OUT = Low 0mT BRP BOP Flux density 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. Unipolar switch characteristic A magnetic hysteresis B HYST keeps BOP and BRP separated by a minimal value. This hysteresis prevents output oscillation near the switching point.

For reverse voltage protection, it is recommended to connect a resistor or a diode in series with the VDD 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) - the resistor has to withstand the power dissipated in reverse voltage condition (PD = VCC2 / R1) When using a diode, a reverse current cannot flow and the voltage drop is almost constant (≈0.7V). Therefore, a 100Ω/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.
