LN4911
Description
LN4911 is a Hall IC (a magnetic sensor) which has 2 times or more sensitivity and a low current consumption of about one fifties pared with our conventional one. Precise magnetic switching points and high temperature stability are achieved through the unique design of the internal circuit. An onboard clock scheme is used to reduce the average operating current of the IC. During the operate phase the IC pares the actual magnetic field detected with the internally pensated switching points. The output Q is switched at the end of each operating phase. If the magnetic field perpendicular to enter the chip and the N-level magnetic field strength reaches a certain value of the CMOS output changes from high to low, and have been known to maintain a low state of the magnetic field perpendicular to enter the S-class chips, then the output again from low to high, the formation of cross-sensitive magnetic field detection effect. LN4911 use of ultra-small package, can be widely...
