Product Description
The MediaTek MT6350V-ANJH is a power management IC (PMIC) designed for use in mobile devices such as smartphones, feature phones, and tablets, as well as in other applications requiring efficient power management solutions. This IC integrates a wide range of power management functions in a single chip, simplifying system designs and reducing the number of components required in the power subsystem of a device.
One of the primary features of the MT6350V-ANJH is its ability to manage multiple voltage rails and provide high-efficiency voltage regulation. Mobile devices require various voltage levels to power different subsystems (processor, memory, display, wireless radios, etc.), and the MT6350V-ANJH handles this with precision. The PMIC supports buck converters for step-down voltage regulation, which ensures that excess energy is not wasted, contributing to better battery efficiency and reduced heat generation. Additionally, boost converters are available to provide higher voltages when necessary, ensuring that devices can operate reliably across different power states and levels.
Another key feature of the MT6350V-ANJH is its advanced battery management capabilities. The IC includes fast-charging support, a critical feature in modern mobile devices. By allowing faster charging times, users can quickly top up their device’s battery without having to wait for extended periods. The PMIC uses intelligent algorithms that adjust charging parameters to prevent damage from overheating or overcharging, ensuring that the battery lasts longer and maintains its health over many charge cycles. Furthermore, the battery protection features built into the MT6350V-ANJH, such as over-voltage, over-current, and over-temperature protection, ensure that the device remains safe during charging and discharging operations, preventing accidents like battery swelling or thermal runaway.
Power sequencing is another important feature of the MT6350V-ANJH. Many modern devices include a variety of power-hungry components that need to be powered up and down in a specific sequence to avoid system instability or hardware failures. The IC is capable of handling sequenced power-up and power-down operations, ensuring that each subsystem receives power at the right time and is properly shut down when not needed. This prevents issues that could arise from improper voltage or current during the device’s power-up and power-down cycles.
In addition to these features, the MT6350V-ANJH also includes integrated components like an LED driver, which can be used for backlighting or status notifications, further reducing the complexity of the design. With its thermal management capabilities, the IC ensures that the system does not overheat, even during intense usage or charging cycles, protecting both the internal components and the user experience.
Overall, the MT6350V-ANJH is an advanced power management IC that provides comprehensive power and charging solutions for mobile devices. It is designed to enhance battery life, optimize charging times, and ensure the safety and stability of the device. By integrating key functions such as multi-rail voltage regulation, battery protection, and fast charging support into a single chip, the MT6350V-ANJH significantly reduces the complexity of power management for device manufacturers while delivering an enhanced user experience for end-users.
Specification
Power Management Features:
Multi-Channel Power Delivery: The MT6350V-ANJH supports multiple voltage rails, which are essential for providing the required power to different components within the mobile device, such as the processor, memory, radio, and peripherals. It can manage several power outputs simultaneously, which is crucial for devices with multiple power demands.
High-Efficiency Voltage Regulation: The IC integrates high-efficiency buck converters (step-down regulators) and boost converters (step-up regulators) that deliver precise voltage regulation to optimize battery life. The efficient power conversion reduces energy loss and extends battery performance, which is vital for mobile devices with demanding power requirements.
Power-Fail Detection: The MT6350V-ANJH includes a power-fail detection mechanism, which ensures the system can detect when the power supply falls below a certain threshold. This feature is particularly useful in preventing system crashes or device failures when the battery level is critically low, allowing for safe shutdown or low-battery warnings.
Battery Charging and Protection:
Fast Charging Support: The MT6350V-ANJH supports fast-charging technologies, which allow devices to charge more quickly by delivering higher currents. The PMIC incorporates intelligent charging algorithms that dynamically adjust the charging rate based on the battery’s condition, temperature, and charging cycle to prevent overheating and extend battery life.
Battery Protection Features: The chip includes a comprehensive set of protection features to ensure safe charging and discharging, such as over-voltage, over-current, short-circuit, and over-temperature protection. These protections help prevent battery damage from electrical faults, thermal events, or sudden spikes in current or voltage.
Li-ion/Li-polymer Battery Support: The MT6350V-ANJH is designed to work with Li-ion and Li-polymer batteries, which are the most common battery chemistries used in modern mobile devices. It provides accurate charge termination and float charging to maximize the battery’s life cycle, ensuring that the battery is safely charged to its optimal voltage level.
Power Sequencing and Management:
Sequenced Power Up/Down: The IC provides power sequencing capabilities, meaning it can control the order in which different power rails are turned on or off. This is critical in managing the start-up and shutdown sequences of complex mobile devices, ensuring that the power is supplied in the correct order to avoid issues like thermal stress or component damage during power transitions.
Load Transient Response: The MT6350V-ANJH is designed to handle rapid load transients, which occur when the power demand from components (such as the CPU or display) suddenly increases or decreases. This helps maintain stable power delivery to the device, even during heavy processing tasks, preventing potential system instability or power failures.
Integrated Features:
LED Driver: The PMIC includes an integrated LED driver, which can be used for backlighting applications or notifications, reducing the need for separate components and simplifying the design of the device.
Thermal Management: The MT6350V-ANJH comes with built-in thermal management capabilities to prevent overheating, ensuring that the device remains within safe operating temperatures. This is particularly important for smartphones and other mobile devices, which can become warm during heavy usage or charging.
