The ME4054M5G with PMIC-Battery Management SOT-23-5 RoHS is a small, low voltage voltage regulator IC manufactured by Micro One. It is designed to manage single-cell Li-ion/Li-polymer battery packs. It includes an input voltage regulator, battery charger, battery voltage monitor, and various system level features. The device is designed to operate from a wide input voltage range and consumes very low quiescent current. It is a SOT-23-5 package, RoHS compliant, and is available in an industrial grade extending its temperature range to -40°C to +105°C. It also supports flexible system sequencing such as charge enable/disable, charge/discharge control, battery preconditioning, and safety timers.
