How low can this PMIC go? Nano
Battery management of always-on, IoT devices present always-on headaches for systems designers who are challenged with making a small-sized device with small batteries that must as last as long as possible — and make it all fit into an increasingly shrinking board. Integrating key functions such as the battery chargers, the microcontroller supply, boost regulator, and LDOs to power the sensors — and battery gauge — Dialog Semiconductor’s fully-integrated nano power DA9070 and DA9073 PMICs consume just 800 nA to 900 nA to maintain the regulation of the various power supplies. Because the devices use a voltage and current monitor inside, there is no need to buy a dedicated fuel gauge
Dialog also demonstrated their recently announced GreenPAK NVM programmable device which allows system engineers to create their part immediately to use on a prototype. The user puts the unprogrammed part into the socket, creates the circuit, pins it out, and sets wires. They then hit “Program,” and the non-volatile memory freezes and the part is ready to use with whatever circuit they created. The company will also program and test for the customer then send the devices on tape and reels.
