72831L15PF is a 4-channel light-sensing Hall IC (integrated circuit) manufactured by Renesas. It is designed to sense magnetic parameters and detect absolute angular speeds. It can be used in applications where the detection of magnetic field changes and angular velocity is required, such as automotive motor and solenoid control, robotics, and more. The output can be used for motor control, for example. It features an integrated 4-channel voltage output, low operating current, and low offset voltage. It is capable of detecting changes in a magnetic field and providing an analytical numerical result as an output voltage.
