GENERAL DESCRIPTION

MA7030S 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 MA7030S 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).

FEATURES

- Micro Power Operation for Battery Applications

- 2.7V to 5.5V battery operation

- Chopper Stabilized Technology

- Operation with South Pole

- High sensitivity and high stability of the magnetic switching points

- Packages: SOT23-3L, SIP-3L(TO-92S), SOT553.
