The normal operation of the automobile engine requires accurate ignition timing, and the crankshaft position sensor is realized through Hall element technology. The crankshaft position sensor is installed on the crankshaft and can sense the rotation position and speed of the crankshaft. When the crankshaft rotates, the magnetic field changes will affect the Hall element and generate an electrical signal, thereby informing the automobile control system of the exact position of the crankshaft and ensuring the accuracy of the ignition timing.
Recommended model: HS211X low-power and high-sensitivity Hall chip
HS211X is an omnipolar magnetic switch developed for high-sensitivity, high-speed, low-power and high-precision applications that integrates tunnel magnetoresistance (TMR) sensors and CMOS technology. HS211X uses a high-precision push-pull half-bridge TMR magnetic sensor and a CMOS integrated circuit, including a TMR voltage generator, a comparator, a Schmitt trigger and a CMOS output circuit, which can convert the changing magnetic field signal into a digital voltage signal output. HS211X provides temperature compensated power through an internal voltage regulator and allows a wide operating voltage range.
HS211X is an ideal choice for many low-power, high-performance applications with its low voltage operation, 1 microampere supply current, extremely high response frequency, wide operating temperature range, and excellent anti-external magnetic interference characteristics. HS211X uses two package forms: SOT23-3 and TO-92S
