AS5013 :Low Power Integrated Hall IC for Human Interface Applications
The AS5013 is a complete Hall Sensor IC for smart navigation key applications to meet the low power requirements and host SW integration challenges for products such as cell phones and smart handheld devices.
Due to the on chip processing engine, system designers are not tasked with integrating complex SW algorithms on their host processor thus leading to rapid development cycles.
The AS5013 single-chip IC includes 5 integrated Hall sensing elements for detecting up to ±2mm lateral displacement, high resolution ADC, XY coordinate and motion detection engine combined with a smart power management controller.
The X and Y positions coordinates and magnetic field information for each Hall sensor element is transmitted over a 2-wire I²C compliant interface to the host processor.
The AS5013 is available in a small 16-pin 4x4x0.55mm QFN package and specified over an operating temperature of -20 to +80℃.
AS5013主要特性:
2.7 to 3.6V operating voltage
Down to 1.7V peripheral supply voltage
Two operating modes:
Idle mode Low Power mode
Less than 3μA current consumption in Idle mode
Low power mode with selectable readout rate
Two interrupt modes
Motion detect
Data ready
Lateral magnet movement radius up to 2mm
High-speed I²C interface
AS5013优势:
Complete system-on-chip
High reliability due to non-contact sensing
Low power consumption
AS5013应用:
The AS5013 is ideal for small factor manual input devices in battery operated equipment, such as
Mobile phones
MP3 players
PDA’s
GPS receivers
Gaming consoles
