1 - 18

1 General Description

The AS5510 is a linear Hall sensor with 10 bit resolution and I²C

interface. It can measure absolute position of lateral movement of a

simple 2-pole magnet. Depending on the magnet size, a lateral

stroke of 0.5~2mm can be measured with air gaps around 1.0mm. To

conserve power, the AS5510 may be switched to a power down state

when it is not used.It is available in a WLCSP package and qualified

for an ambient temperature range from -30°C to +85°C.
