HAL 5xy
Hall Effect Sensor Family in CMOS technology Release Note: Revision bars indicate significant changes to the previous edition. 1. Introduction The HAL 5xy family consists of different Hall switches produced in CMOS technology. All sensors include a temperature-compensated Hall plate with active offset compensation, a comparator, and an open-drain output transistor. The comparator compares the actual magnetic flux through the Hall plate (Hall voltage) with the fixed reference values (switching points). Accordingly, the output transistor is switched on or off. The sensors of this family differ in the switching behavior and the switching points. The active offset compensation leads to constant magnetic characteristics over supply voltage and temperature range. In addition, the magnetic parameters are robust against mechanical stress effects. The sensors are designed for industrial and automotive applications and operate with supply voltages from 3.8 V to 24 V in the ambient temperature range from -40 C up to 150 C. All sensors are available in the SMD-package SOT89B-1 and in the leaded versions TO92UA-1 and TO92UA-2.

Latching Sensors: The output turns low with the magnetic south pole on the branded side of the package and turns high with the magnetic north pole on the branded side. The output does not change if the magnetic field is removed. For changing the output state, the opposite magnetic field polarity must be applied.
Bipolar Switching Sensors: The output turns low with the magnetic south pole on the branded side of the package and turns high with the magnetic north pole on the branded side. The output state is not defined for all sensors if the magnetic field is removed again. Some sensors will change the output state and some sensors will not.

1.4. Operating Junction Temperature Range The Hall sensors from Micronas are specified to the chip temperature (junction temperature TJ). A: TJ = -40 C to +170 C K: TJ = -40 C to +140 C Note: Due to the high power dissipation at high current consumption, there is a difference between the ambient temperature (TA) and junction temperature. Please refer to Section 5.1. on page 46 for details.
Unipolar Switching Sensors: The output turns low with the magnetic south pole on the branded side of the package and turns high if the magnetic field is removed. The sensor does not respond to the magnetic north pole on the branded side.
Unipolar Switching Sensors with Inverted Output: The output turns high with the magnetic south pole on the branded side of the package and turns low if the magnetic field is removed. The sensor does not respond to the magnetic north pole on the branded side.
Unipolar Switching Sensors with Inverted Output Sensitive to North Pole: The output turns high with the magnetic north pole on the branded side of the package and turns low if the magnetic field is removed. The sensor does not respond to the magnetic south pole on the branded side.

1.6. Solderability and Welding
DATA SHEET
Soldering During soldering reflow processing and manual reworking, a component body temperature of 260 C should not be exceeded.
Welding Device terminals should be compatible with laser and resistance welding. Please note that the success of the welding process is subject to different welding parameters which will vary according to the welding technique used. A very close control of the welding parameters is absolutely necessary in order to reach satisfying results. Micronas, therefore, does not give any implied or express warranty as to the ability to weld the component.

2. Functional Description The HAL 5xx sensors are monolithic integrated circuits which switch in response to magnetic fields. If a magnetic field with flux lines perpendicular to the sensitive area is applied to the sensor, the biased Hall plate forces a Hall voltage proportional to this field. The Hall voltage is compared with the actual threshold level in the comparator. The temperature-dependent bias increases the supply voltage of the Hall plates and adjusts the switching points to the decreasing induction of magnets at higher temperatures. If the magnetic field exceeds the threshold levels, the open drain output switches to the appropriate state. The built-in hysteresis eliminates oscillation and provides switching behavior of output without bouncing. Magnetic offset caused by mechanical stress is compensated for by using the "switching offset compensation technique". Thus, an internal oscillator provides a two-phase clock. The Hall voltage is sampled at the end of the first phase. At the end of the second phase, both sampled and actual Hall voltages are averaged and compared with the actual switching point. Subsequently, the open drain output switches to the appropriate state. The time from crossing the magnetic switching level to switching of output can vary between zero and 1/fosc. Shunt protection devices clamp voltage peaks at the output pin and VDD pin together with external series resistors. Reverse current is limited at the VDD pin by an internal series resistor up to -15 V. No external reverse protection diode is needed at the VDD pin for reverse voltages ranging from 0 V to -15 V.

HAL 501
4. Type Description 4.1. HAL 501 The HAL 501 is the most sensitive sensor of this family with bipolar switching behavior (see Fig. 4.1.). The output turns low with the magnetic south pole on the branded side of the package and turns high with the magnetic north pole on the branded side. The output state is not defined for all sensors if the magnetic field is removed again. Some sensors will change the output state and some sensors will not. For correct functioning in the application, the sensor requires both magnetic polarities (north and south) on the branded side of the package. Applications
DATA SHEET
The HAL 501 is the optimal sensor for applications with alternating magnetic signals and weak magnetic amplitude at the sensor position such as: - applications with large air gap or weak magnets, - rotating speed measurement, - commutation of brushless DC motors, and - CAM shaft sensors, and - magnetic encoders. Output Voltage VO BHYS
Magnetic Features: - switching type: bipolar - very high sensitivity - typical BON: 0.5 mT at room temperature - typical BOFF: -0.7 mT at room temperature - operates with static magnetic fields and dynamic magnetic fields up to 10 kHz BOFF 0 BON B VOL

5. Application Notes 5.1. Ambient Temperature Due to the internal power dissipation, the temperature on the silicon chip (junction temperature TJ) is higher than the temperature outside the package (ambient temperature TA).
T J = T A + T
DATA SHEET
5.3. Start-Up Behavior Due to the active offset compensation, the sensors have an initialization time (enable time ten(O)) after applying the supply voltage. The parameter ten(O) is specified in the Electrical Characteristics (see page 15). During the initialization time, the output state is not defined and the output can toggle. After ten(O), the output will be low if the applied magnetic field B is above BON. The output will be high if B is below BOFF. In case of sensors with an inverted switching behavior (HAL 516 ... HAL 519), the output state will be high if B > BOFF and low if B < BON. Note: For magnetic fields between BOFF and BON, the output state of the HAL sensor will be either low or high after applying VDD. In order to achieve a defined output state, the applied magnetic field must be above BON, respectively, below BOFF.
Under static conditions and continuous operation, the following equation applies:
T = IDD x VDD x R th
For all sensors, the junction temperature range TJ is specified. The maximum ambient temperature TAmax can be calculated as:
T Amax = T Jmax - T
5.4. EMC and ESD For applications with disturbances on the supply line or radiated disturbances, a series resistor and a capacitor are recommended (see Fig. 5-1). The series resistor and the capacitor should be placed as closely as possible to the HAL sensor. Applications with this arrangement passed the EMC tests according to the product standards ISO 7637. Please contact Micronas for the detailed investigation reports with the EMC and ESD results.
For typical values, use the typical parameters. For worst case calculation, use the max. parameters for IDD and Rth, and the max. value for VDD from the application.
5.2. Extended Operating Conditions All sensors fulfil the electrical and magnetic characteristics when operated within the Recommended Operating Conditions (see page 14). Supply Voltage Below 3.8 V Typically, the sensors operate with supply voltages above 3 V, however, below 3.8 V some characteristics may be outside the specification.
RV 220 1 VEMC VP 4.7 nF VDD OUT 3 20 pF 2 GND RL 1.2 k
Note: The functionality of the sensor below 3.8 V is not tested on a regular base. For special test conditions, please contact Micronas.
