MA7030N is a three-terminal Hall Effect sensor device with an output driver, mainly
designed for battery–operation, hand-held equipment (such as Cellular and Cordless Phone,
PDA).
The MA7030N is a unipolar Hall effect sensor IC. If a magnetic flux density larger than
threshold Bop, OUT is turned on(low). The output state is held until a magnetic flux density
reversal falls below Brp causing OUT to be turned off (high).
