OCH1501
OCH1501 is Micro Power Unipolar Hall-effect Sensor Switch manufactured by Orient Chip.
Description
- Features
The OCH1501 Unipolar Hall effect sensor IC is
- Micro power consumption ideal for fabricated from mixed signal CMOS technology. It is battery-powered applications prised of one Hall plate and a CMOS output driver,
- Input Voltage Range: 2.2V to 4.5V mainly designed for battery-operation, hand-held
- Very High Sensitivity Hall Sensor equipment (such as Cellular and Cordless Phone,
- Chopper stabilized amplifier stage
PAD). The total power consumption in normal
- Good RF noise immunity operation is typically 28μW with a 2.8V power source.
- Open Drain Output
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
M operating point (BOP), the output will be turned on
(low), the output is held until B is lower than release
O point (BRP), and then turned off. The OCH1501 is available in TSOT23-3L
.C Package. Operating temperature range of the
OCH1501 is from -40°C to 85°C. To minimize the BOM cost, capacitors of the
P MLCC type are supported, and only one external ponent is needed to plete the application
I circuit.
