The QMC6309H is a three-axis magnetic sensor, which integrates magnetic sensors and signal condition ASIC into one silicon chip. This wafer level chip scale package (WLCSP) is targeted for applications such as e-compass, map rotation, gaming and personal navigation in mobile and wearable devices.

The QMC6309H is based on state-of-the-art, high resolution, magneto-resistive technology. Along with the custom-designed 16-bit ADC ASIC, it offers the advantages of low noise, high accuracy, low power consumption, offset cancellation and temperature compensations. QMC6309H enables 1° to 2° compass heading accuracy. The I2C serial bus allows for easy interface.

The QMC6309H is in a 0.8x0.8x0.5mm3 surface mount 4-pin WLCSP package.
