Power management integrated circuits (PMICs) provide a one-stop solution for safely managing battery power and other components within an electronic system. PMICs are integrated circuit chips that contain either an analog or a digital control system for system power management. The goal of PMICs is to maximize the power efficiency of portable electronics and other battery-powered devices. This makes them an invaluable tool for modern electronics designers. One of the important PMIC may be BQ29410DCT3R, which is especially suitable for Lithium ion or Lithium Polymer Battery Chargers, Battery Packs, and or Solar Energy Storage Units.

Application Field

The BQ29410DCT3R is a PMIC Battery Management System suitable for Lithium ion or Lithium Polymer battery charging, Battery Packs, and Solar Energy Storage Units. With a wide input voltage range of 3.2V to 5.5V and input currents up to 3A, this PMIC is ideal for a variety of applications. For example, it could be used for industrial and consumer electronics, like connected devices, cordless kitchen equipment, drones, home automation, and smart clothing. Moreover, the BQ29410DCT3R can be implemented in portable electronics, like laptops, cameras, tablets, smart phones and wearables. Additionally, the device may be used to power consumer electronics and industrial applications.

Working Principle

The BQ29410DCT3R is a system power management IC that comprises several main components and peripherals. The components are arranged in a power management subsystem, consisting of three blocks: a battery charger, a boost converter and an LDO regulator. The charger component is responsible for charging the battery. It features a low-ripple, 1.5MHz switch frequency to reduce board space and emissions and minimise the bill of materials. The charger also includes a battery temperature monitor circuit, allowing it to maximise the charging quality and extend the battery life by making sure that the battery is not overcharged or damaged. It also features a smarter charge algorithm to guarantee faster, more reliable charge times and charging profiles.

The boost converter is the second component of the power subsystem. It is used to supply power from the system’s main power supply to other components and peripherals that require higher voltages. It functions by increasing the voltage of the incoming current, and can also be used to supply power to a 3.3V/20mA external peripheral.

The LDO regulator is the final component of the power management subsystem. It works by regulating the incoming current and maintaining a constant voltage output. It is designed to maximise power efficiency and reduce power loss, ensuring that the system is only drawing the necessary amount of power.

The BQ29410DCT3R also includes several other peripheral features, such as a battery voltage monitor to prevent overvoltage conditions, a power good signal output to monitor the system power status, an enable signal output to prevent power-on leakage current and an external bootstrap voltage input for high voltage operations. Additionally, the system has a few additional features designed to improve system reliability and safety, such as overvoltage protection, overcurrent protection, over-temperature protection and undervoltage protection.

The BQ29410DCT3R is an ideal PMIC for Lithium ion or Lithium Polymer Battery Chargers, Battery Packs, and or Solar Energy Storage Units. It provides a one-stop solution for safely managing battery power and other components within an electronic system. The device’s combination of on-chip features and robust system protection makes it a perfect fit for a wide range of applications, from consumer electronics to industrial applications. It ensures fast, reliable operation and efficient system power management.
