OCH168B
OCH168B is Micro Power Omnipolar Hall-effect Sensor Switch manufactured by Orient Chip.
Micro Power Omnipolar Hall-effect Sensor Switch
- General Description
- Features
The OCH168B Omnipolar Hall effect sensor IC is
- Micro power consumption ideal for battery-powered fabricated from mixed signal CMOS technology. It is applications prised of two Hall plates and a OD output driver,
- Omnipolar (operation with magnetic field of either mainly designed for battery-operation, hand-held north or south pole), easy to use as output switches with equipment (such as Cellular and Cordless Phone, both North and South pole
PDA). The total power consumption in normal
- Input Voltage Range: 2.4V to 5.5V 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
M no magnetic field. While the magnetic flux density (B) is larger than operating point (BOP), the output will be
O turned on (low), the output is held until B is lower than release point (BRP), and then turned off.
.C The OCH168B is available in many flexible packaging options, such as SIP-3L, TSOT23-3L. Operating temperature range of the OCH168B is from
P -40°C to 85°C. I To minimize the BOM cost, capacitors of the H MLCC type are supported, and only one external ponent are needed to plete the application
-C circuit.
