AK09970N

Low-power Consumption when Battery Life is Critical
The AK09970N can operate using only a few μA, thus consuming a very low current that satisfies a demand of IoT products, (Refer to the Specification Table). It contributes to a long battery life of a product that needs constant acquisition of sensor data to monitor an object’s status.

Magnetic Field Output (Digital)/ Data Ready Alert (DRDY bit)
The AK09970N measures magnetic field on all tri-axis via intermittent drive and outputs the result as digital data, (supporting I?C / SPI communications).
It outputs a Data Ready alert to the dedicated register when the measurement data is updated. (0.25 / 0.5 / 1 / 10 / 20 / 15 / 100Hz interval modes or single measurement mode is selectable for intermittent drive options.)

Magnetic Event Interrupt Function
The AK09970N has magnetic event interrupt pins. Two thresholds can be programmed for each axis, (setting the resolution equal to the measuring resolution). When a magnetic field that exceeds the threshold is sent, the AK09970N outputs a “Magnetic Event” interrupt to registers or external output pins. The magnetic event that causes an interrupt output that can be selected freely by setting a register. (Data Ready alert mentioned in 3 can also be output from an interrupt pin). Two interrupt pins are available for magnetic event: the INT pin for push-pull output and the ODIN pin for open-drain output. Therefore, the output format can be selected depending on the customer’s product.
