Power consumption of the step counter is typically less than 30μA, maximizing battery life in portable devices. The sensor can be used to put wearables into sleep mode even during step-counting, thereby helping to reduce overall power consumption. BMA456 sensor is easily designed into space-constrained wearable applications such as fitness trackers, smartwatches, and hearables.
The hearable feature set integrates tap, double-tap, and triple-tap for intuitive user interaction, no-motion, and motion for optimized power management, activity recognition, and step counting for fitness applications. The 0.65mm height is ideally suited for wearable and hearable devices.
