MicroPower, Ultra -sensitive Hall Effect Switch GENERAL DESCRIPTION MA7001 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 outp ut is switch with either north or South Pole of sufficient strength will turn the output on (low). The output will be turned off (high) under no magnetic field. While the magnetic flux density (B) is larger than operate point (Bop), the output will be turn ed on (low); the output is latched until B is lower than release point (Brp) and then 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.
