LM3658SD-A/NOPB General Description

Operating in five distinct modes, including pre-qualification, constant-current, constant-voltage, top-off, and maintenance modes, the LM3658SD-A/NOPB also functions as a linear regulator in "LDO mode" when no battery is present but the AC wall adapter is connected. Advanced features such as thermal regulation, battery temperature measurement, safety timers, and LED status indication outputs further contribute to reliable and efficient battery charging capabilities with this IC

Key Features

Compact and efficient battery charging solution
Safe, reliable, and thermal regulated performance
Status indication LEDs for easy monitoring
USB or AC adapter compatible charger available
