Description

The MT6328 is power management system chip optimized for 2G/3G/4G handsets and smart phones, containing 5 buck converters and 28 LDOs optimized for specific 2G/3G/4G smart phone subsystems.
LED drivers support up to 2 channels of LEDs with independent control. Flexible control includes register mode, PWM mode and breath mode. Sophisticated controls are available for powerup, battery charging and the RTC alarm. MT6328 is optimized for maximum battery life, allowing the RTC circuit to stay alive without a battery for several hours.
