NPM1100-CAAB-R7

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 DC/DC buck regulator with configurable dual mode output. nPM1100 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 400 mA through USB, and delivers up to 150 mA of current to power external components with regulated voltage. A minimum of five passive components are required for operation. It is the perfect companion for nRF52 and nRF53 multiprotocol SoCs in battery powered designs and the device functions without a control interface. Low quiescent current (IQ) extends battery life for 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.
