ABLIC launches voltage monitoring ICs

The S-82F9 Series and S-82D9 Series are voltage monitoring ICs for simple remain battery power displays with 5 LED or 4 LED indicators. These solutions achieve monitoring of multiple voltages on a single IC which contributes to saving space, and can also carry out voltage monitoring of batteries at low power consumption because they can be operated without a microcontroller.

Typically, when lighting up LEDs for use as a residual power display in power tools and other applications, functions are used where components are combined discretely or are equipped with a microcontroller, etc. However, these solutions have disadvantages including that when components are combined discretely, it increases the number of components, requiring more space on the board, and if a microcontroller is used, it increases the amount of current consumption.

The S-82F9 Series and S-82D9 Series can solve those challenges to current battery remaining indications by utilising functionalities of voltage monitoring ICs.

The features of these new products include the ability to select products to suit applications with the addition of driving 4 and 5 indicators ICs to ABLIC's existing S-8229 for driving 3 indicators product, which contribute to lower power consumption and space saving in applications by not requiring a microcontroller; lower power consumption when the LEDs are off in the A Series which is equipped with an EN pin, and the capability to monitor high voltage in the B Series which is equipped with a SENSE pin; and the ability to select either 'full charge all on' which increases the number of lit LEDs based on the battery voltage, or 'individual step voltage on,' which changes which LEDs are lit based on battery voltage

Going forward, ABLIC will continue to fully leverage our technology to develop lithium-ion battery protection ICs and other IC products for peripheral devices with even greater accuracy and higher performance, and which can be used for applications in a wide range of areas.
