COM OCH178 Micro Power Omnipolar Hall-effect Sensor Switch ◼ General Description The OCH178 Omnipolar Hall-effect Sensor IC is fabricated from mixed signal CMOS technology.
It is comprised of two Hall plates and a CMOS output driver, mainly designed for battery-operation, hand-held equipment (such as Cellular and Cordless Phone, PDA).
The total power consumption in normal operation is typically 24μW with a 3V power source.
Either north or south poles of sufficient strength will turn the output on.
The output will be turned off under no magnetic field.
While the magnetic flux density (B) is larger than operating point (BOP), the output will be turned on (low), the output is held until B is lower than release point (BRP), and then turned off.
The OCH178 is available in many flexible packaging options, such as DFN1616-6L and DFN1616-3L.
Operating temperature range of the OCH178 is from -40°C to 85°C.
To minimize the BOM cost, capacitors of the MLCC type are supporte...
