3 HALxx Hall Effect Sensor Family in CMOS technology Release Notes: Revision bars indicate significant changes to the previous edition. 1. Introduction The HALxx 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 4 V in the ambient temperature range from 4 C up to 1 C. All sensors are available in a SMD-package (SOT-89A) and in a leaded version (TO-9UA). The introduction of the additional SMD-package SOT-89B is planned for Features: switching offset compensation at typically 6 khz operates from 3.8 V to 4 V supply voltage overvoltage protection at all pins reverse-voltage protection at -pin magnetic characteristics are robust against mechanical stress effects short-circuit protected open-drain output by thermal shut down operates with static magnetic fields and dynamic magnetic fields up to 1 khz constant switching points over a wide supply voltage range the decrease of magnetic flux density caused by rising temperature in the sensor system is compensated by a built-in negative temperature coefficient of the magnetic characteristics ideal sensor for applications in extreme automotive and industrial environments EMC corresponding to DIN Family Overview The types differ according to the magnetic flux density values for the magnetic switching points, the temperature behavior of the magnetic switching points, and the mode of switching.

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. MICRONAS INTERMETALL 3

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.

5 HALxx. Functional Description HALxx The HAL xx 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. 1 GND Reverse Voltage & Overvoltage Protection Hall Plate Temperature Dependent Bias Switch Hysteresis Control Comparator Clock Fig. 1: HALxx block diagram Short Circuit & Overvoltage Protection Output OUT 3 Magnetic offset caused by mechanical stress is compensated for by using the switching offset compensation technique. Therefore, 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/f osc. f osc B t Shunt protection devices clamp voltage peaks at the Output-Pin and -Pin together with external series resistors. Reverse current is limited at the -Pin by an internal series resistor up to 1 V. No external reverse protection diode is needed at the -Pin for reverse voltages ranging from V to 1 V.

30 HAL HAL 16 The HAL 16 is the most sensitive unipolar switching sensor with an inverted output of this family (see Fig. 4 33). 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. For correct functioning in the application, the sensor requires only the magnetic south pole on the branded side of the package. Applications The HAL 16 is the optimal sensor for all applications with one magnetic polarity and weak magnetic amplitude at the sensor position where an inverted output signal is required such as: applications with large airgap or weak magnets, solid state switches, contactless solution to replace micro switches, position and end point detection, and rotating speed measurement. In the HAL xx family, the HAL 6 is a sensor with the same magnetic characteristics but with a normal output characteristic.

36 HALxx. Application Notes.1. Ambient Temperature Due to the internal power dissipation, the temperature on the silicon chip (junction temperature T J ) is higher than the temperature outside the package (ambient temperature T A ). T J = T A + T At static conditions, the following equation is valid: T = I DD * * R th For typical values, use the typical parameters. For worst case calculation, use the max. parameters for I DD and R th, and the max. value for from the application. For all sensors, the junction temperature range T J is specified. The maximum ambient temperature T Amax can be calculated as: T Amax = T Jmax T.. Extended Operating Conditions All sensors fulfill the electrical and magnetic characteristics when operated within the Recommended Operating Conditions (see page 7). 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. state, the applied magnetic field must be above max, respectively, below min..4. EMC For applications with disturbances on the supply line or radiated disturbances, a series resistor and a capacitor are recommended (see figures 1 and ). The series resistor and the capacitor should be placed as closely as possible to the HAL sensor.

Start-up Behavior Due to the active offset compensation, the sensors have an initialization time (enable time t en(o) ) after applying the supply voltage. The parameter t en(o) is specified in the Electrical Characteristics (see page 8). During the initialization time, the output state is not defined and the output can oscillate. After t en(o), the output will be low if the applied magnetic field B is above. The output will be high if B is below. In case of sensors with an inverted switching behavior (HAL HAL18), the output state will be high if B > and low if B <. 4.7 nf Fig. : Test circuit GND 3 pf For magnetic fields between and, the output state of the HAL sensor after applying will be either low or high.
