nPM1100
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.
• Ultra-high efficiency prolongs battery life or allows for use of smaller and less costly batteries • Small solution size leaves space for additional features without increasing product size • No software control • Automatic USB port detection minimizes development time
