1.2 Applications
Ideal for power management of 2G, 3G, smart
phones and other portable systems.
MT6329 for MediaTek 3G smart phone platform,
MT6575.
phones, especially those based on the
MediaTek MT6575 system solution. MT6329
contains 15 buck converters and 21 LDOs,
which are optimized for specific 2G/3G/smart
phone subsystems.
MT6329 provides dual-channel, 0.7W into 8Ω,
high efficiency Class AB/D audio amplifiers and
flexibility for various applications of backlight
LED drivers. It supports up to 6 WLEDs in
parallel or alternative series 10WLED
configurations. Flexible control keeps high
power efficiency while supporting multiple
drivers.
Sophisticated controls are available for power-
up, battery charging and the RTC alarm.
MT6329 is optimized for maximum battery life.
The selectable 1-step or 2-step RTC LDO
design makes MT6329 suitable for different
RTC modules in BB chips. It allows the RTC
circuit to stay alive without a battery for several
hours. The battery charger in MT6329 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.
Some multi-purpose pins enable MT6329 to be
configured in various applications. MT6329
implements dedicate analog switches, KPLED
and 450mA FLASH LED driver.
MT6329 adopts I2C interface to control buck
converters (dedicate 2 pins DVFS control and 3
pins PA_SEL control), LDOs, Class AB/D,
various drivers and charger. Besides, it provides
enhanced safety control and protocol for
handshaking with BB.
MT6329 is available in a 155-pin TFBGA
package. The operating temperature ranges
from -25 to +85°C.
1.3 General Descriptions
MT6329 is a power management system chip
optimized for 2G/3G handsets and smart
