GENERAL DESCRIPTION
MA7008 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 MA7008 is an 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
- 1.65V to 5.5V battery operation
- Chopper Stabilized Technology
- Operation with North or South Pole
- High sensitivity and high stability of the magnetic switching points
- Packages: SOT23-3L, SIP-3L(TO-92S), SOT553.
