PMIC simplifies power management system design

Stephen Law   


NORDIC SEMICONDUCTOR nPM1300 Power Management IC (PMIC) provides two ultra-efficient buck converters, two load switches/Low Drop Out voltage converters (LDOs) and integrated battery charging, suitable for battery-operated applications. Product reduces an end-product’s Bill-of-Materials (BoM) by combining circuitry that typically requires five or more discrete components into a single chip. product launch is accompanied by roll-out of corresponding Evaluation Kit (EK) and the nPM PowerUP PC app, which make it simple for developers to evaluate, configure, and implement the nPM1300 PMIC without having to write any code. PMIC also brings enhanced system management features and accurate fuel gauging for low power wireless applications. The algorithm-based fuel gauge functionality of the device uses voltage, current, and temperature monitoring for higher accuracy than voltage-based fuel gauges, while keeping the PMIC’s own power consumption considerably lower than coulomb counter-type fuel gauges.
