OCH166A
OCH166A is Micro Power Omnipolar Hall-effect Sensor Switch manufactured by Orient Chip.
Micro Power Omnipolar Hall-effect Sensor Switch
- General Description
- Features
The OCH166A omnipolar Hall effect sensor IC is
- Micro power consumption ideal for battery-powered fabricated from mixed signal CMOS technology. It is applications prised of one Hall plate and a CMOS 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 equipment (such as Cellular and Cordless Phone,
- Input Voltage Range: 1.65V to 3.6V
PAD). The total power consumption in normal
- Very High Sensitivity Hall Sensor operation is typically 4μW with a 1.8V power source.
- Chopper stabilized amplifier stage
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 OCH166A is available in SOT23-3L, .C DFN1616-6L-EP, DFN1216-4L, DFN1616-6L and SOT553 package. Operating temperature range of the OCH166A is from -40°C to 85°C.
P To minimize the BOM cost, capacitors of the
MLCC type are supported, and only one external
I ponent is needed to plete the application circuit.
- Good RF noise immunity
- DFN1216-4L, SOT23-3L,DFN1616-6L-EP,
