1.8 V Supply voltage, Low current consumption, high sensitivity CMOS Hall IC Operates for Alternating magnetic field directions
FEATURES
High sensitivity (4 mT max) due to offset cancel circuit and a new sample and hold circuit.
Small current by using intermittent action. (average supply current : 55 µA typ. sampling cycle : 660 µs typ at VCC = 1.8 V)
Power supply voltage : 1.65 to 3.6 V Operating ambient temperature : – 40 to + 85 C CMOS inverter output. (no pull-up resistance) Wheel keys / Track ball applications. Magnetic fields polarity change from S to N or
from N to S can be detected. Contactless switch in various moving devices to
involve reliabilities and dusty circumstances. 5 pin Plastic Small Surface Mount Package.
