Therefore these magnetic field sensor devices have no amplifier offset voltage which in bipolar designed devices is the main reason for temperature sensitive output signal drift. The sensors output transistor will be in the latched- on state (Bop) in the presence of a sufficiently strong South-Pole magnetic field, facing the marked side of the SIP package. The sensor output will be in the latched-off state (B,,) in the presence of a North-Pole field. temperature specifications to meet the needs of various commercial and industrial applications. Typical applications for these devices are: sensing of speed, linear position, and angular position. Though there are many applications where the FUS3881 sensor IC can be used, its performances have been optimized for commutation applications of 5V and 12V brushless DC motors.
