Extremely Compact Single-chip PMIC Solution From Nordice Semiconductor at Rutronik
The unit features thermal battery protection and automatic selection of three charging modes: automatic trickle charge, constant current, and constant voltage.
Nordic nPM1100 is a dedicated power management IC (PMIC) with a configurable dual-mode buck regulator and integrated battery charger. It is designed as a complementary component to Nordic‘s nRF52® and nRF53® series of system-on-chips (SoCs) to ensure reliable power supply and stable operation while maximizing battery life through high efficiency and low quiescent currents. It can also be used as a generic PMIC device for any other suitable application. The extremely compact (2.075 x 2.075 mm) WLCSP package is ideal for applications in wearables, connected medical devices, smart home sensors and controls, remote controls and game controllers, and other size-constrained applications.
The integrated battery charger is designed to charge lithium-ion and lithium-polymer batteries to a selectable termination voltage of 4.1 or 4.2 V and supports cell chemistries with a nominal voltage of 3.6 or 3.7 V respectively.
The maximum charging current is selectable via a resistor from 20 mA up to 400 mA. The charger also has a discharge current limiter and is JEITA compliant.
The high-efficiency step-down regulator can deliver up to 150 mA of current at a selectable output voltage of 1.8, 2.1, 2.7, or 3.0 V. It features soft start and automatic transition between hysteresis and PWM modes. It also enables a forced PWM mode to ensure clean operation.
Uncomplicated Start-up
The nPM1100 Evaluation Kit makes an uncomplicated evaluation of the nPM1100 PMIC and its functions possible - developers do not need their own test hardware.
