MA7006 (Preliminary) MicroPower, Ultra -sensitive Hall Effect Switch GENERAL DESCRIPTION MA7006 is a three-terminal Hall Effect sensor device with an output driver. The device is using CMOS process includes an on -chip Hall voltage generator for magnetic sensing, a comparator that amplifies the Hall voltage, and a Schmitt trigger to provide switching hysteresis for noise rejection, and push -pull output, and an internal temperature compensated circuits. This method reduces the offset voltage normally caused by device over molding and thermal stress. The output 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 turned on (low); the output is latched until B is lower than release point (Brp) and then turned off (high). FEATURES - 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 - Low Profile SOT23-3L Package PIN ASSIGNMENT The package of MA7006 is SOT23-3L; the pin assignment is given by: VDD OUT ( Marking Side ) GND Name Description VDD Supply Voltage OUT Output GND Ground.
