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 powerup, 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 precharge 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.

3.2.1 Power-On/Off Sequence

PMIC handles the powe-on and -off of the handset. If the battery voltage is neither in the UVLO state (VBAT ≥ 3.4V) nor in the thermal condition, there are three methods to power on the handset system:

1) Pulling PWRKEY low (the user pushes PWRKEY), 2) Pulling PWRBB high (baseband BB_WakeUp) and 3) Valid charger plug-in.

According to different battery voltage (VBAT) and phone state, control signals and regulators will have different responses.

Power on/off sequence

The power-on/off sequence controlled by the “control” and “reset generator” is shown in the figure below.

Note that the figure above only shows one power-on/off. MT6329 handles the powe-on and -off of the handset. The following three different ways methods switch on the handset (when VBAT ≥ 3.4V):

1. Pushing PWRKEY (pulling the PWRKEY pin to low level) Pulling PWRKEY low is typical method to turn on the handset. The VCORE and VPROC buck converters will be turned on first then VIO18 and VIO28 LDOs are turned on sequentially. The supplies for the baseband are ready, and the system reset ends at the moment when all the default-on regulators are fully turned on to ensure correct timing and function. After that, the baseband sends the PWRBB signal back to PMIC for acknowledgement. To successfully power on the handset, PWRKEY should be kept low until PMIC receives PWRBB from the baseband.

2. RTC module generates PWRBB to wake up the system

If the RTC module is scheduled to wake up the handset at some time, the PWRBB signal will be directly sent to PMIC. In this case, PWRBB becomes high at specific moment and allows PMIC power-on as the sequence described above. This is called the RTC alarm.

3. Valid charger plug-in (CHRIN voltage within valid range) The charger plug-in will also turn on the handset if the charger is valid (no OVP takes place). However, if the battery voltage is too low to power on the handset (UVLO state), the system will not be turned on by any of the three methods. In this case, the charger will charge the battery first, and the handset will be powered on automatically as long as the battery voltage is high enough.

Under-voltage lockout (UVLO)

The UVLO state in PMIC prevents start-up if the initial voltage of the main battery is below the 3.2V threshold. It ensures that the handset is powered on with the battery in good condition. The UVLO function is performed by a hysteretic comparator which ensures smooth power-on sequence. In addition, when the battery voltage is getting lower, it will enter the UVLO stat,e and PMIC will be turned off by itself, except for VRTC LDO, to prevent further discharging. Once PMIC enters the UVLO state, it will draw low quiescent current. RTC LDO will still be working until DDLO disables it.

Deep discharge lockout (DDLO)

PMIC will enter the deep discharge lockout (DDLO) state when the battery voltage drops below 2.5V. In this state, VRTC LDO will be shut down. Otherwise, it will draw very low quiescent current to prevent further discharging or even damage to the cells.

Reset

PMIC contains a reset control circuit which takes effect at both power-up and power-down. The RESETB pin is held low in the beginning of power-up and returns to high after the pre-determined

delay time. The delay time is controlled by a large counter, which uses the clock from the internal ringoscillator. At power-off, the RESETB pin will return to low immediately without any delay.

If the die temperature of PMIC exceeds 150°C, PMIC will automatically disable all LDOs except for VRTC. Once the over-temperature state is resolved, a new power-on sequence will be required to enable the LDOs.

3.2.2 The Battery Charger (Charger Controller)

The charger controller senses the charger input voltage from either a standard AC-DC adaptor or an USB charger. When the charger input voltage is within a pre-determined range, the charging process will be activated. This detector resists higher input voltages than other parts of PMIC.

3.2.2.1 Block Descriptions

3.2.2.1.1 Charger Detection

Whenever an invalid charging source is detected (> 7.0V), the charger detector will stop the charging process immediately to avoid burning out the chip or even the phone. Furthermore, if the charger-in

level is not high enough (< 4.3V), the charger will also be disabled to avoid improper charging behavior.

3.2.2.1.2 Charging Control

When the charger is active, the charger controller will manage the charging phase according to the battery status. During the charging period, the battery voltage is constantly monitored. The battery charger supports pre-charge mode (VBAT < 3.2V, PMIC power-off state), CC mode (constant current mode or fast charging mode at the range of 3.2V < VBAT < 4.2V) and CV mode (constant voltage mode) to optimize the charging procedure for Li-ion battery. See the figure below for the charging states diagram.

Pre-charge mode

When the battery voltage is in the UVLO state, the charger will operate in the pre-charge mode. There are two steps in this mode. While the battery voltage is deeply discharged below 2.2V, PRECC0 trickle charging current is applied to the battery.

MEDIATEK CONFIDENTIAL

The PRECC1 trickle charging current is about 56mA continuous current when VBAT is under 2.2V.
