Sun Roof
Hall switches are used to determine the position of the window pane by measuring the motion direction as well as counting the revolutions of the window lifter motor. This can be realized either by using dual-Hall-plate switches or with a cheaper single-Hall-plate solution that counts the revolutions while the motion direction of the motor is determined by the control unit.

Door Lock
Hall switches are used to detect whether the car doors are locked or not. By skipping the third wire, the 2-wire sensor type is preferred for this kind of application in order to save costs.
Brushless actuators allow tamper-proof lock design.

Buckle Switch
Hall switches are often used to detect whether the seat belts are used and the buckle holder is latched. Due to the greater distance from the sensor to the control unit, a 2-wire Hall switch is often the preferred sensor type for cost-saving reasons. Depending on the application setup, a unipolar or latching type can be used.

Bending Lights
Adaptive Headlights technology enhances the safety and convenience of the driver, especially when driving at night. For instance, the headlights are swiveled horizontally towards the inside of a bend when cornering.
Hall-effect sensors are widely used to detect the orientation of the light beam within the Adaptive Headlights module. The “zero-position” of the swivel module, i.e. the position in the straight-ahead position of the vehicle, is generally given by a Hall-effect switch, sometime programmable to perfectly match the switching point to the zero-position.

HVAC
HVAC actuators are typically small stepper motors. Micronas HVC products offer suitable small and highly integrated one-chip all-inclusive solutions with low current ripple (acoustic noise), supporting LIN auto-addressing (bus shunt method), different driving schemes (current-controlled, auto speed) and stall detection.

Blower and Flap Control – AGM
The Active Grill Shutter application is deploying quickly in automotive as it provides with efficient reduction of emission and gas savings. Conventional actuators use stepper motors but there is a trends towards BLDC. TDK-Micronas’ highly integrated on-chip solutions enable higher torque at higher temperature, smaller size and more sophisticated control.

Blower and Flap Control – LED Fans
Typically used for LED light cooling and mist removal, LED fans require efficient actuators with very small footprint. HVC all-in-one integrated solutions match the power requirements for BLDC drive in a single-chip solution without the need for external MOSFETs.

Seat - Position
Like the buckle switch, the seat position detection is one part of the airbag control system. The task of the Hall switch is to determine in what zone the seat is currently positioned along the seat track. 2-wire switches are the preferred solution.

Seat - Climate Control
Seat Climate Control fans are more and more deployed into vehicles. HVC all-in-one integrated solutions match the power requirements for BLDC drive in a single-chip solution without the need for external MOSFETs.

Charging Aadapter Lock
EV and HEV need a Charging Adapter Lock for safety reasons. The connector is locked to avoid that it is removed while charging the car. The position of the charging connector lock can be easily and safely detected via a 2D position sensor.

Body & Comfort
Important electrification trend in the vehicle body compartment. Contactless sensors and electric motors are replacing mechanical and hydraulic systems for higher comfort and better reliability. TDK Corporation has the largest magnetic-field sensor portfolio to address the wide diversity of requirements in those applications and next generation components addressing the needs for lower power consumption and system cost efficiency. TDK also provides fully integrated servo-drive controllers for BLDC and stepper motors as well as switches and direct-angle sensors for motor position detection.
