The R5478N187CD-TR-FF with Battery Management 1-Cell Li-ion Battery Protection IC is an integrated circuit (IC) designed for use in battery managed systems. It is manufactured by Nisshinbo and has a lead form factor in an eighth-inch package. The IC features an integrated 1-cell Li-ion battery protection function, consuming minimal power while protecting one Li-ion cell from overcharge, over-discharge, and other fault conditions. It also features a low-current sleep mode, active-low sleep enable signal, two dedicated GPIOs, and Over Discharge Charge Detection (ODCD) with adjustable voltage thresholds. The IC also includes an onboard charge/discharge balance current sense resistor for improved system efficiency. This IC is typically used in applications such as cell phones, tablet computers, and other similar mobile devices.
