The switch does not respond to the magnetic north pole on the branded side. 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 switch does not respond to the magnetic north pole on the branded side. Unipolar Inverted The switch turns to low current consumption with the magnetic south pole on the branded side of the package and turns to high consumption if the magnetic field is removed. The switch does not respond to the magnetic north pole on the branded side. 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 switch does not respond to the magnetic north pole on the branded side. Bipolar (3-wire only) 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 if the magnetic field is removed again. Some switches will change the output state and some switches will not. Latching The switch turns to high current consumption with the magnetic south pole on the branded side of the package and turns to low consumption with the magnetic north pole on the branded side. The current consumption does not change if the magnetic field is removed. For changing the current consumption, the opposite magnetic field polarity must be applied. 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. 2-Wire Switch The current is monitored and the switch operates as indicated by the type of switch. Current level is as speciified within the data sheet. 3-Wire Switch The voltage is monitored and the switch operates as indicated according to the type of switch. Selection by Application – Automotive Recommended Solution Comment BLDC Motor Commutation HAL 15xy 3-wire latching e.g. HAL 1502, HAL 1501 –– –– –– –– Clutch and Brake Pedal Position Detection Brake: HAL 15xy 2-wire unipolar –– ISO 26262 compliant for safety critical applications –– High ESD protection ±8 kV (HBM) –– Provided with open drain output or with current interface High temperature resistance up to 150 °C (TA) Low current consumption of only 1.6 mA High switching accuracy Small SOT23 JEDEC package e.g. HAL 1564 Clutch: HAL 15xy 3-wire unipolar e.g. HAL 1503, HAL 1508 Gear Shift Lever HAL 15xy 3-wire unipolar e.g. HAL 1507 Window Lifter HAL 7xy Dual Hall plate switch HAL 15xy 3-wire or 2-wire latching e.g. HAL 1502, HAL 1501 –– Price-attractive solution to provide actual position of the gear shift lever with two sensors –– Small SOT23 JEDEC package –– ISO 26262 compliance for safety-critical applications Sensor purpose: motion direction and revolution counting of the window lifter motor. HAL 7xy dual Hall plate switches: –– Highest switching accuracy –– Motion direction and revolution counting by one IC HAL 15xy single Hall plate swiches: –– Price-attractive solution –– High threshold accuracy thanks to lowest output jitter of max. 0.72 µs (RMS) –– ISO 26262 compliance for safety critical applications Explanation: HAL 15xy counts the motor revolutions while the motors’ motion direction is determined by the control unit. Software algorithms help to specify the accuracy of the motion direction. Seat Track Position Seat Belt Presence Detection HAL 15xy 2-wire unipolar e.g.HAL1563, HAL1566 –– –– –– –– ISO 26262 compliance for safety-critical applications Power supply down to 2.7 V ESD protection ±8 kV (HBM) 2-wire IC allows to skip one wire HAL 15xy 2-wire unipolar or latching –– –– –– –– ISO 26262 compliant for safety-critical applications Power supply down to 2.7 V ESD protection ±8 kV (HBM) 2-wire IC allows to skip one wire e.g.HAL1566, HAL1562 Selection by Application – Industrial Recommended Solution Comment Alternative BLDC Motor Commutation HAL 1502 or HAL 1501 These Hall switches in SOT23 packages offer high switching accuracy and low power consumption and are used for the commutation of brushless DC motors e.g. in power tools, washing machines, dish washers, ventilation fans or electric bikes. HAL 505 Rotation and Speed Sensor HAL 15xy The HAL 15xy switch family enable short output switching time and is used to detect or to control the speed of motors, fans or liquid flow, e.g. in power tools, home appliances, white goods (water delivery) and wheel-speed in electric vehicles and electric bikes. Proximity and Position Sensor HAL 15xy The HAL 15xy switch family is offered in small packages and enable accurate switching points and a short output refresh time. They are used as proximity sensors to detect the end-position to stop the motor or to detect the absence or presence of material, e.g. rolling shutter, or doors, or factory automation. Geartooth Sensor HAL 300, HAL 320 Differential Hall switches can be used for speed measurement and position detection for RPM management, e.g. geartooth speed with back-bias magnet or rotating multi-pole-ring in process automation control. Door Lock HAL 1565, HAL 1564 These 2-wire Hall switches with high switching accuracy, low power consumption and integrated wirebreak detection can be used to detect if the door is closed or open, e.g. in home appliances or white good applications. Magnetic Encoder HAL 710, HAL 730 (with direction signal) These Hall switches with two independent Hall plates and outputs (quadrature interface, A&B) and constant switching points can be used in linear encoder applications for position and direction detection, e.g. in factory robots or CNC machines, or for BDC motor control.
