NPM1100-QDAA-R

nPM1100-QDAA-R is an integrated power management IC (PMIC) with a linear-mode lithium-ion/lithium-polymer battery charger. It has a highly efficient DC/DC buck regulator with configurable dual mode output. This is an extremely compact PMIC device, created for space constrained applications that have a small lithium-ion or lithium-polymer battery. It is compatible with all nRF52 and nRF53 series SoCs, supports charging batteries at up to 400mA through USB, and delivers up to 150mA of current to power external components with regulated voltage. A minimum of five passive components are required for operation. Application includes health/fitness sensor and monitor devices (advanced wearables), mouse, keyboard, multi-touch trackpad (advanced computer peripherals and I/O devices), remote controls, gaming controllers (interactive entertainment devices).
