It features a built-in color screen that can display all SPI communications in real-time, using a standard FTDI USB serial chip to communicate with the PC, eliminating the need for special drivers. The SPIDriver evaluation board includes 3.3 V … Read more
Some battery-powered products, if not designed properly, may exhibit a phenomenon where the battery fails to charge after being over-discharged. The reason is generally that these products lack a dynamic power path management feature in their charging design. When the battery is depleted and charging begins, the product typically activates certain functions to display charging … Read more
Introduction to EMMC Circuits EMMC (Embedded Multi Media Card) is a standard specification established by the MMC Association, primarily targeting embedded storage for products such as mobile phones and tablets. EMMC integrates a controller within the package, providing a standard interface and managing flash memory.The principle circuit’s 8-bit data signals are shown in Figure 8-38, … Read more

The rapid development of the electronics industry is inseparable from electricity. Since we need to use electricity, it involves a control circuit and a power circuit. A key part of the power circuit is the Power Management Integrated Circuit (PMIC). For those with years of experience in the electronics industry or newcomers to power design, … Read more
Whether for consumer electronics, industrial control, IoT devices, or for communication networks and automotive electronic systems, Power Management ICs (PMICs) are a critical part of the system. PMICs contain a large number of analog circuits, and due to uncontrollable factors during production, the final mass-produced analog circuits may differ from the initial design, affecting the … Read more
1. What is PMIC Power Management Integrated Circuit (PMIC) is the Chinese term for 电源管理集成电路, which is characterized by high integration, encapsulating traditional multi-output power supplies into a single chip, making multi-power applications more efficient and compact. PMIC is an indispensable key component in today’s electronic devices, providing power for various devices from mobile phones … Read more
According to reports from Electronic Enthusiasts Network (by Li Ningyuan), there are three power supply design solutions—fully discrete, fully integrated, and partially integrated. Among these, integrated PMICs package traditional multi-output power supplies into a single chip, resulting in higher efficiency and smaller size for multi-power applications. This fully integrated power solution is essential in wearable … Read more
