PMIC Comparison from Flagship
The battery is a critical component to mobile devices such as smartphones, because they’re what makes the device mobile. As demand for these devices is driven by power-hungry new features such as 5G and bright displays, it’s no wonder that smartphones account for over 5 GWh per year of energy used by Li-ion batteries.
While larger and denser batteries is an obvious priority, this approach has its limits, and smartphone makers rely on power and battery management integrated circuits (PMIC/BMIC) to optimize battery use and charging. Mobile and consumer applications in fact account for the lion’s share of the power IC market, representing over $10B in revenue.
Among these chips are battery charger controller ICs, which use bipolar CMOS DMOS (BCD) technology to regulate the current flow during battery charging. This function is critical to charge efficiently the battery while maintaining its health.
In this report, we compare the batter charger controller ICs in 5 ultra-premium smartphone flagships, the Apple iPhone 15 Pro Max, Oppo Find X6, Google Pixel 7 Pro, Samsung Galaxy S23 Ultra & Xiaomi 13 Ultra. It includes detailed physical analysis of the packaging and die and uses optical microscopy, cross-sectional scanning electron microscopy (SEM), and delayering analyses to identify the technologies and processes used.
Then this information is combined with supply chain analysis to simulate their fabrication costs. We present a summary and comparison of the physical and technical findings for each component as well as their manufacturing cost breakdowns.
