General Description

AS1560 is a low-power digital linear Hall sensor in
measuring the intensity of the magnetic flux through
selecting options of the various sensitivity with the low
power consumption providing a built-in 16 bits ADC
digital output. It can also detect the open/close state for
many applications by one or multiple external magnets. This sensor is comprised of a Hall element, an
offset cancellation circuitry, a programmable gain
amplifier, a 16-bits low power ADC, and control logic in
a single chip. The adjustment of the open/close state
threshold values, the magnetic polarity, and the
operation period can be programmed through I2C
interface. The software package supports to convert
the magnetic strength into the angle or distance by
detecting intensity of flux between the external magnet
and the sensing element. Because the small WLCSP
package, the low current consumption, and the stable
performance, the device can be used in the hand set
and consumer electronics and any other industries. One of the typical applications in the smart phone is
the lid opening angle measurement system. A key feature of the device is its Programmable
Hall switch, which allows users to define the
comparison range via the comparison register through
I²C. Additionally, the output logic can be configured to
toggle between high and low states when the detected
magnetic field meets the preset threshold. The device is a RoHs and Green compliant
DFN2020-6L package.
