nPM1100 - Nordic Semiconductor
nPM1100 Product / 2021-05-20nPM1100nPM1100 is an integrated power Management IC (PMIC) with a linear-mode lithium-ion/lithium-polymerbattery charger in a compact mm WLCSP package. It has a highly efficient, dual-mode configurableoutput DC/DC buck is an extremely compact PMIC device, created for space constrained applications with a smalllithium-ion or lithium-polymer battery. It is compatible with all nRF52 and nRF53 Series SoCs and supportscharging batteries at up to 500 mA through USB, and also delivers up to 150 mA of current to powerexternal components with regulated minimum of five passive components are required for operation and the device functions without acontrol interface. It is the perfect companion for nRF52 and nRF53 multiprotocol SoCs in battery powereddesigns. Low quiescent current (IQ) extends battery life during shipping and storage with Ship mode, or inoperation using auto-controlled hysteretic buck mode for high efficiency down to 1 A loads.
SYSREG also implements configurable current limiting from VBUS , and USB port detection. When VBUS is disconnected, SYSREG ensures the device enters Ultra-Low Power mode to minimize quiescent current. Reverse current protection is enabled when VBUS<VBAT. See SYSREG — System regulator on page 15 for more information and electrical parameters.
