The OCH167 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 39渭W 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 OCH167 is available in many flexible
packaging options, such as TSOT23-3L,
DFN1616-6L, DFN1616-3L, DFN2020-3L, and
DFN1216-4L. Operating temperature range of the
OCH167 is from -40掳C to 85掳C.
