1. Overview

IC for smart watch and smart band

The smart watch is a typical example of a wearable device. The smart watch, which is evolving day by day, has become a gateway to a new lifestyle; it senses what its wearer does and its surroundings at all times, and can fulfill a variety of functions when combined with a smart phone or other devices. In their pursuit of ever higher performance in the evolution of the smart watch, engineers face two unavoidable hurdles: the extension of battery life and the need for more compact devices .
Building on 70 years of watch manufacture technology, ABLIC can deliver an IC that resolves these issues. To extend battery life, we offer the ideal combination of a battery protection IC providing a power-saving feature to reduce product battery power in storage, together with a Linear Regulator and switching regulator that are amongst the world's top class in low operating current consumption.
Our Linear Regulators and switching regulators, which eliminate the need for a divider resistor for battery monitoring, and our lineup of WLP packages and 0.8mm square compact resin packages, will lead to more compact smart watches. Enhancement of smart watch performance is supported by our power-supply ICs, high-accuracy temperature sensors in compact packages, and ultra-compact wireless power receiver control ICs with minimum number of parts.
