The XB5609A Battery Management IC with SOT23-5 package is manufactured by XySemi and is compliant with the RoHS standards. It is a 3-cell battery protection IC designed to provide protection from overcharge, overdischarge, short circuit, and battery over temperature conditions. It was designed to protect 1-3 series Li-Ion or Li-Polymer battery packs and features advanced charging parameters, low quiescent current, low power dissipation, and programmable minimum voltage thresholds. Additionally, it includes an onboard charger and a thermal watchdog for cell temperature monitoring. For applications such as LED lighting, Bluetooth headphones, and other portable electronic devices, the XB5609A is ideal due to its low power consumption and its ability to protect the battery packs from overcharge and overdischarge.
