2.5 Functional Block Description
The chopped Hall IC switch comprises a Hall probe, bias generator, compensation circuits, oscillator and output transistor. The bias generator provides currents for the Hall probe and the active circuits. Compensation circuits stabilize the temperature behavior and reduce influence of technology variations. The active error compensation (chopping technique) re jects offsets in the signal path and the influence of mechanical stress to the Hall probe caused by moldin g and soldering processes and other thermal stress in the package. The chopped measurement principle together with the threshold generator and the comparator ensures highly accurate and temperature stable magnetic thresholds.

2.6 Default Start-up Behavior
The magnetic thresholds exhibit a hysteresis B HYS =B OP -B RP. In case of a power-on with a magnetic field B within hysteresis (BOP >B>B RP) the output of the sensor is set to the pull up voltage level (VQ) per default. After the first crossing of B OP or B RP of the magnetic field the internal de cision logic is set to the corresponding magnetic input value. VDDA is the internal supply voltage which is following the external supply voltage VDD. This means for B > BOP the output is switching, for B < BRP and BOP >B>B RP the output stays at VQ.

3.2 Absolute Maximum Ratings
Attention: Stresses above the max. values listed here may cause permanent damage to the device. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Maximum ratings are absolute ratings; exceeding only one of these values may cause irreversible damage to the integrated circuit. Calculation of the dissipated power PDIS and junction temperature TJ of the chip (SOT23 example): e.g. for: VDD = 5 V, IS = 2 mA, VQSAT = 0.5 V, IQ = 1 mA Power dissipation: PDIS = 5 V x 2 mA + 0.5 V x 1 mA = 10 mW + 0.5 mW = 10.5 mW Temperature ΔT = RthJA x PDIS = 300 K/W x 10.5 mW = 3.15 K For TA = 150 °C: TJ = TA + ΔT = 150 °C + 3.15 K = 153.15 °C Table 3 Absolute Maximum Rating Parameters Parameter Symbol Values Unit Note or Test Condition Min.
