Introduction The HAL 11x family consists of different Hall switches produced in CMOS technology. All sensors include a temperature-compensated Hall plate, 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. The sensors are designed for industrial and automotive applications and operate with supply voltages from 4.5 V to 24 V in the ambient temperature range from –40 °C up to 125 °C. All sensors are available in an SMD-package (SOT-89B) and in a leaded version (TO-92UA). 1.1. Features 1.3. Marking Code – operates from 4.5 V to 24 V supply voltage – overvoltage protection – reverse-voltage protection at VDD-pin – short-circuit protected open-drain output by thermal shut down – operates with static magnetic fields and dynamic magnetic fields up to 20 kHz – stable 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 HAL114 HAL115 All Hall sensors have a marking on the package surface (branded side). This marking includes the name of the sensor and the temperature range. Type K 114K 115K Temperature Range E 114E 115E C 114C 115C 1.2. Family Overview The types differ according to the mode of switching. Type HAL114 HAL115 Switching Behavior unipolar bipolar see Page 10 12 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. 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. Micronas 3 HAL11x 1.4. Operating Junction Temperature Range The Hall sensors from Micronas are specified to the chip temperature (junction temperature TJ). K: TJ = –40 °C to +140 °C E: TJ = –40 °C to +100 °C C: TJ = 0 °C to +100 °C The relationship between ambient temperature (TA) and junction temperature is explained in section 5.2. on page 14. 1.5. Hall Sensor Package Codes HALXXXPA-T Temperature Range: K, E, or C Package: SF for SOT-89B UA for TO-92UA (SO for SOT-89A) Type: 11x Example: HAL114UA-E → Type: 114 → Package: TO-92UA → Temperature Range: TJ = –40 °C to +100 °C Hall sensors are available in a wide variety of packaging versions and quantities. For more detailed information, please refer to the brochure: “Ordering Codes for Hall Sensors”. 1.6. Solderability all packages: according to IEC68-2-58 During soldering reflow processing and manual reworking, a component body temperature of 260 °C should not be exceeded. Components stored in the original packaging should provide a shelf life of at least 12 months, starting from the date code printed on the labels, even in environments as extreme as 40 °C and 90% relative humidity. VDD 1 OUT VDD 1 Reverse Voltage & Overvoltage Protection 2. Functional Description The HAL 11x 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. 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.

Type Description 4.1. HAL 114 The HAL 114 is a unipolar switching sensor (see Fig. 4–1). 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. For correct functioning in the application, the sensor requires only the magnetic south pole on the branded side of the package.

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.

Application Notes 5.1. Application Circuit The HAL 11x sensors can operate without external components. 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 sensor. RV 220 Ω 1 VDD 5.2. 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). TJ = TA + ∆T At static conditions, the following equation is valid: ∆T = IDD * VDD * Rth 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. VDD OUT 3 RL For all sensors, the junction temperature range TJ is specified. The maximum ambient temperature TAmax can be calculated as: TAmax = TJmax – ∆T 5.3. Extended Operating Conditions All sensors fulfill the electrical and magnetic characteristics when operated within the Recommended Operating Conditions (see page 6). Please use the sensors of the HAL 5xx family if lower operation voltage, lower current consumption or tighter magnetic specifications required. 5.4.

This parameter ten(O) is specified in the Electrical Characteristics (see page 7). During the initialization time, the output state is not defined and can toggle. After ten(O), the output will be low if the applied magnetic field B is above BON or high if B is below BOFF. For magnetic fields between BOFF and BON, the output state of the HAL sensor after applying VDD will be either low or high. In order to achieve a well-defined output state, the applied magnetic field must be above BONmax, respectively, below BOFFmin. 2.2 µ/50 V C1 2.2 µ /50 V C2 Fig. 5–2: Recommended application circuit for DC fans 14 Micronas HAL11x Micronas 15 HAL11x 6.
