AS5510
Linear Hall Sensor with I²C Output
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 and SOIC8 package and qualified for an ambient temperature range from -30°C to 85°C. Ordering Information and Content Guide appear at end of datasheet.
Key Benefits & Features
The benefits and features of AS5510, Linear Hall sensor with I²C output are listed below:
Features
Contactless position measurement Power down mode Simple configuration over the I2C interface 10bit resolution Programmable sensitivity Available in two different packages: WLCSP & SOIC8
Applications
The AS5510 is ideal for: • Position sensing • Servo drive feedback • Camera lens control • Closed loop position control.
