1.3 General Descriptions
MT6323 is a power management system chip
optimized for 2G/3G handsets and smart
phones, especially based on the MediaTek
MT6572 system solution. MT6323 contains 3
buck converters and 24 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 several 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.
Some multi-purpose pins enable MT6323 to be
configured in various applications.
MT6323 adopts SPI interface and SRCLKEN
control pin to control buck converters, LDOs,
Class AB/D, various drivers and charger.
Besides, it provides enhanced safety control
and protocol for handshaking with BB.
MT6323 is available in a VFBGA - 145L
package. The operating temperature ranges
from -25 to +85°C.
