S-8254ABEFT-TB-S

Battery Management Overview

The S-8254ABEFT-TB-S is a battery protection IC designed for 3 to 4 series lithium-ion or lithium-polymer cells. It operates within a supply voltage range of 2 V to 24 V and features an operating supply current of 12 uA. The device supports overcharge detection voltages from 3.90 V to 4.45 V with 50 mV steps and ±25 mV accuracy, and overdischarge detection from 2.0 V to 3.0 V with 100 mV steps. It provides three-stage overcurrent protection with specific thresholds including 0.05 V to 0.30 V ranges. The component is housed in a 16-TSSOP package and functions reliably between -40°C and +85°C.
