Energy-friendly power management ICs (PMICs) from Silicon Labs, the EFP01 family are companion chips for EFR32 wireless devices and EFM32 microcontrollers. They enable developers to choose the optimal battery type and chemistries for their applications. Target applications include IoT sensors, asset tags, smart meters, home and building automation, security, and health and wellness products. The PMICs also enable developers to control a product’s power supply over multiple output rails and voltages.
