OCH1501
OCH1501
Micro Power Unipolar Hall-effect Sensor Switch
General Description
The OCH1501 Unipolar Hall effect sensor IC is
fabricated from mixed signal CMOS technology. It is
comprised of one Hall plate and a CMOS output driver,
mainly designed for battery-operation, hand-held
equipment (such as Cellular and Cordless Phone,
PAD). The total power consumption in normal
operation is typically 28μW with a 2.8V power source.
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 OCH1501 is available in TSOT23-3L
Package. Operating temperature range of the
OCH1501 is from -40°C to 85°C.
To minimize the BOM cost, capacitors of the
MLCC type are supported, and only one external
component is needed to complete the application
circuit.
