1.3 General Descriptions
MT6323 is a power management system chip optimized for 2G/3G handts and smart phones, especially bad on the MediaTek
MT6572 system solution. MT6323 contains 3 buck converters and 23 LDOs, which are optimized for specific 2G/3G/smart phone subsystems.
MT6323 provides mono 0.7W into 8Ω, high efficiency Class AB/D audio amplifiers and flexibility for various applications of indicator LED drivers. It supports up to 4 channel LEDs with independent controlled. Flexible control includes: register mode, PWM mode and breath mode.
Sophisticated controls are available for power-up, battery charging and the RTC alarm.
MT6323 is optimized for maximum battery life. It allows the RTC circuit to stay alive without a battery for veral hours. The battery charger in MT6323 supports lithium- ion (Li-ion) battery and provides pre-charge indication. The charger input voltage can be up to 10V and allows USB charging, too.
