Depending on the magnetic field, the output of a linear Hall sensor does not have a discrete switching state, but provides a signal proportional to the magnetic field strength. This output signal can be delivered as an analog output voltage, a pulse-width-modulated signal (PWM) or even as a modern bus protocol (SENT). Different packages are available: through hole SMD, single or dual die configuration, with our without integrated capacitors. Linear Hall sensors from TDK-Micronas are designed for industrial and automotive applications.
The linear Hall sensor portfolio comprises:
