A power management integrated circuit (PMIC) is a highly integrated device with many functional circuit blocks onboard. The high level of integration provides many benefits, including reduced printed circuit board (PCB) space, simpler design, faster time to market, and a reduced bill of material (BoM) cost. Analog Devices’ PMICs with battery chargers or USB power managers address battery charging and provide multiple system rails in portable products, all in a compact form factor. PowerPath control allows for seamless transitions and manages power flow between different input sources such as a wall adapter, USB port, and lithium battery while preferentially providing power to the system load.

Analog Devices’ power system management (PSM) ICs and sequencers allow you to keep existing analog power systems while adding new capabilities: output trimming (±0.25% precision), margining, sequencing, nonvolatile fault recording, and digital monitoring data (on voltage, current, power, energy, temperature, and faults).
