OCH1502S MicroPower Unipolar Hall-effect Sensor Switch
The OCH1502S 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 Smart phone and PAD). The total power consumption in normal operation is typically 4.5μW with a 2.8V power source. North 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 less than operating point (BOPS), the output will be turned on (low), the output is held until B is higher than release point (BRPS), and then turned off(High).
The OCH1502S is available in DFN1616-6L-EP and DFN1216-4L-EP Package. Operating temperature range of the OCH1502S 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.
