Consumer IoT 
From mobile devices like smartphones to wearables such as fitness trackers and everyday gadgets like toys, consumer devices are becoming smarter and more connected. The convergence of low-power multi-core processors, intelligent sensors, high-density memory, advanced power management circuits, and embedded security technologies with internet access has fostered new classes of products that deliver productivity, convenience, and entertainment.
Applications
Sensing
Sensing solutions are enhancing quality of life by enabling us to track our activity levels and monitor a variety of health parameters. Human body sensors output magnitude signals in the millivolt and microvolt ranges. Our integrated devices for wearable health applications combine sensors with amplification and conversion circuits within a single die or package.

Optical Sensors
Processing
The availability of low-cost, low-power multi-core processors has contributed to the rise of innovative new consumer products. Smartphones, tablets, and similar mobile devices require powerful processing capabilities to deliver everywhere computing. For wearable applications in particular, processing capability is one of the key selection criteria for a microcontroller. A system partitioning strategy can help determine which system functions are best integrated into the microcontroller and which can be handled externally.
Power
With many smart, connected consumer products powered by small batteries, such as button or coin cell types, low power consumption and long battery life are in the spotlight. Simple, low-power monitoring circuits effectively assess the health and state-of-charge (SOC) of these batteries—without significantly affecting their SOC. Fuel gauge ICs with built-in security deliver precise measurements of current, voltage, and temperature. Efficient power management ICs (PMICs) provide multiple voltage rails along with battery management capabilities, helping to extend battery life in mobile applications. Safe, efficient battery chargers available in a small solution size support IoT devices that are powered by rechargeable, high energy density Li-ion batteries.
