Product description
The MT6328V/A is a sophisticated PMIC designed to provide efficient and safe power management in mobile devices. It integrates multiple features that enhance the device's overall performance while protecting sensitive components and optimizing power consumption.
Power Regulation: The PMIC includes DC-DC converters that supply high-power components like the processor and display with stable voltage. The LDO regulators ensure that low-power components such as sensors and memory receive clean, stable power, which is essential for reliable operation.
Battery Charging Management: The MT6328V/A integrates fast charging technology, reducing the time it takes to recharge the device. It supports Li-ion and Li-polymer batteries, two common chemistries in mobile devices, and ensures safe charging by implementing overvoltage, overcurrent, and thermal protection to prevent battery damage.
Thermal Protection: The PMIC employs thermal throttling, which reduces power delivery to the device's high-power components when the temperature rises above a predefined threshold, helping to prevent overheating. If the temperature continues to increase, thermal shutdown automatically powers off the device, preventing heat-related damage.
Power Sequencing: The PMIC ensures that power is delivered to various components in the correct order during device startup, which is essential for proper initialization and stable operation of the system.
Protection Features: The MT6328V/A includes several essential protection mechanisms, such as overvoltage protection, undervoltage protection, overcurrent protection, and short-circuit protection, which help prevent electrical faults and ensure the safety and reliability of the device.
Battery Health Monitoring: The PMIC monitors the voltage, current, and temperature of the battery, ensuring that charging cycles are optimized and the battery remains healthy over time. This helps extend battery life and maintain its performance throughout the device's lifetime.
I2C Communication Interface: The I2C interface allows the PMIC to communicate with the system processor, enabling real-time adjustments to power settings based on the device's workload and power demands.
Specification parameters
DC-DC Converters:
The DC-DC converters are responsible for regulating power to high-power components such as the processor and display. The converters help to ensure minimal energy loss while delivering stable and reliable voltage.
LDO Regulators:
The LDO regulators are responsible for providing clean, low-noise power to components that require precision, such as memory and sensors.
