R5449 Series High-performance 1-Cell Li-ion Battery Protection IC with Built-in Driver for High-side Nch FETs and Temperature Protection

2023-07-09 NISSHINBO

The R5449 is one-cell Li-ion / polymer battery protection IC for high-side Nch FETs and temperature protection,provides overcharge, overdischarge, discharge / charge overcurrent, and temperature detections. The 1-Cell Li-ion Battery Protection IC can drive external high-side Nch MOSFETs and provides a high-accuracy detection at overcharge and overcurrent, and a high-accuracy charge inhibition for 0V battery.


Furthermore, the IC can reduce the supply current after overdischarge detection to a minimum by stopping the internal circuits. Using the CTL pin can forcefully enter the IC into standby mode.
