The austriamicrosystems AS5510 introduced this week is a linear Hall sensor IC that features 10-bit digital output resolution and a 1.46 x 1.1 mm chip scale package. The AS5510 includes an I²C 2-wire serial interface for switching between four different sensitivity ranges and for simple transmission of data to a microcontroller.
Designed for mobile consumer products with space constraints such as zoom or autofocus camera systems, the AS5510 can measure the absolute position of a simple 2-pole magnet for a typical lateral stroke of 0.5 - 2 mm with air gaps of 1.0 mm. With stronger magnets even higher lateral strokes and air gaps are possible.
To minimize power consumption, the AS5510 can switch to a power-down mode with a current consumption of 25 µA. The I²C interface provides a fast connection to the microcontroller without requiring additional analog to digital conversion.
The AS5510 linear Hall sensor IC is specified over the -30°C to +85°C temperature range, comes in a 6-pin WLCSP and operates from a 2.5V to 3.6V supply voltage.
Samples are available now.
