Home Products nPM1100 한글 简体 Eng nPM1100 Power Management IC Ultra-small form-factor Power Management IC (PMIC) for charging batteries and power delivery. The nPM1100 is a dedicated power management IC (PMIC) with a highly efficient dual-mode configurable buck regulator and integrated battery charger. It is designed as a complementary component to Nordic’s nRF52® Series and nRF53® Series System-on-Chips (SoCs) to ensure reliable power delivery and stable operation, whilst 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. Its extremely compact form factor makes it ideal for advanced wearables, connected medical devices, and other size constrained applications. PCB area usage can be as low as 23 mm2. The integrated battery charger is designed to charge lithium-ion and lithium-polymer batteries on a termination voltage selectable to 4.1 or 4.2 V supporting cell chemistries with a nominal voltage of 3.6 and 3.7 V, respectively. It includes battery thermal protection and automatic selection of three charging modes: automatic trickle, constant current and constant voltage. The maximum charge current is resistor selectable from 20 mA up to 400 mA. The charger also features a discharge current limitation and is JEITA compliant. The PMIC is USB compatible and allow for charging batteries through USB, with automatic port detection. The highly efficient step-down buck 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 startup and automatic transition between hysteretic and PWM modes. It also allows for forced PWM mode to ensure clean power operation. The power conversion efficiency goes up as far as to 92 % while maintaining a small footprint of only 27 mm2, including passive components. To read more download the nPM1100 product brief.
