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 voltage regulator and switching regulator that are amongst the world’s top class in low operating current consumption.
Our voltage 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, surface-mount UV sensor ICs, high-accuracy temperature sensors in compact packages, and ultra-compact wireless power receiver control ICs with minimum number of parts.
ABLIC ICs are ideal for Smart Watches and Smart Bands

Battery Protection IC S-82B1B
Power-saving (PS) function, which prevents complete depletion of the battery pack during storage!
A low current consumption mode (50nA max.) can be engaged by inputting an external signal to the PS pin. Thanks to this mode, discharge current of the battery pack and current consumption of the protection circuit can be virtually eliminated during shipping of the battery pack.
Voltage Regulator S-1740/1741 and
Switching Regulator S-85S1P
With a supply voltage divided outputsmall footprint
Simple battery monitoring! IC with a “supply voltage divided output”!
The supply voltage divided output of this IC separates input voltage (VIN) and outputs it to VIN/2 or VIN/3.
This function can connect the supply voltage divided output from the IC directly to the A/D converter of the low-voltage microcontroller, allowing the microcontroller to monitor the battery voltage without a divider resistor. For more information, refer to “Supply voltage divided output.”
The compact package of this supply voltage divided output IC facilitates its smaller footprint.
