S-8255(20-Pin TSSOP package)

ABLIC Inc. (hereinafter “ABLIC”), a semiconductor manufacturer, launched the S-8255A/B Series, a monitoring IC for 3- to 5-serial cell batteries.

The new product, the S-8255A/B Series has the following features. (1) In addition to common overcharge and overdischarge protection functionalities, it also provides temperature protection to enable configuration of circuits offering even greater safety. (2) A power-saving function prevents dark current from causing loss of battery pack capacity during shipping. (3) An overcharge detection voltage accuracy of ±20mV and a low power consumption of 19uA max. despite high performance place it among the top performers in the industry.

The switching pins can be used to extend protection to 3, 4 or 5 serial cells. The cascade function of the S-8255A Series allows you to configure protection circuits comprising six or more cells to accommodate a wide variety of applications.

This figure shows an example of a 10-cell protection circuit using the S-8255A Series.
