R5436T504BA

R5436T Series 3 to 5 Serial Cell Li-Ion or Li-Polymer Battery Protection IC NO.EA-322-191206 OUTLINE The R5436T is an overcharge, overdischarge and overcurrent protection IC for Li-ion or Li-polymer secondary battery. Overcharge, Overdischarge, Charge Overcurrent and Discharge Overcurrent for 3 to 5 serial cells can be detected. By cascade connection using the R5436T, it is also possible to protect 6-serial or more cells rechargeable battery pack. The R5436T provides a cell-balancing function to equalize imbalance between cells, and it provides an open-wire detection to detect a broken wire between a battery and the circuit board. The open-wire detection is optionally selectable.
