Battery Power Management IC Lithium Ion/Polymer 24-QFN (4x4) nPM1100 is an integrated Power Management IC (PMIC) with a linear-mode lithium-ion/lithium-polymer battery charger in a compact 2.1x2.1 mm WLCSP package. It has a highly efficient, dual-mode configurable output DC/DC buck regulator. nPM1100 is an extremely compact PMIC device, created for space constrained applications with a small lithium-ion or lithium-polymer battery. It is compatible with all nRF52 and nRF53 Series SoCs and supports charging batteries at up to 500 mA through USB, and also delivers up to 150 mA of current to power external components with regulated voltage. A minimum of five passive components are required for operation and the device functions without a control interface. It is the perfect companion for nRF52 and nRF53 multiprotocol SoCs in battery powered designs. Low quiescent current (IQ) extends battery life during shipping and storage with Ship mode, or in operation using auto-controlled hysteretic buck mode for high efficiency down to 1 µA loads. Charge and error indication LED drivers are built in. Charge profile limits are configurable and VBUS current limits can be fixed or auto-controlled with on-chip USB port detection. • 400 mA linear battery charger • Linear charger for lithium-ion/lithium-polymer batteries • Adjustable charge current from 20 mA to 400 mA • Selectable termination voltage of 4.1 V or 4.2 V • Automatic trickle, constant current, and constant voltage charging • Battery thermal protection • Discharge current limitation • JEITA compliant • Li-ion/Li-polymer USB battery charger with a high efficiency buck regulator • 800 nA - Typical quiescent current • 460 nA - Shipping mode quiescent current • Thermal protection • Input regulator • USB compatible current limit of 100 mA and 500 mA • 4.1 V to 6.7 V input voltage range for normal operation • 20 V overvoltage protection • Reverse current protection • 3.0 V to 5.5 V system voltage output • USB port detection supporting the following types: • SDP • CDP/DCP • 1.8 V to 3.0 V, 150 mA step-down buck regulator • Step-down buck regulator with up to 92% efficiency • Automatic transition between hysteretic and pulse width modulation (PWM) modes • Forced PWM mode for clean power operation • Pin-selectable output voltage (1.8 V, 2.1 V, 2.7 V, 3.0 V) • Soft start-up • LED drivers for charger state indication • 5 mA low side LED driver for charging indication • 5 mA low side LED driver for error indication • 2.3 V to 4.35 V battery operating input range • 2.1x2.1 mm WLCSP package • Suitable for two layer PCB design #CommonPartsLibrary #IntegratedCircuit #NordicSemiconductor #nPM1100 #PMIC #BatteryCharger #PowerManagement #LiIon #LiPolymer #BuckConverter #Wearables #IoT #WirelessSensor #LowPowerDesign #USBCharging #EmbeddedSystems #nRF52 #nRF53 #PortableElectronics
