APW7703C
General Description
The APW7703C is a Power Management IC (PMIC) with a battery powered system designed to provide complete
Power Management solution for the camera applications. The IC operates from a single supply voltage of 2.7V to 5.
5V allowing it to be used in Adapter/USB or 1 Cell battery applications. The APW7703C is designed to provide
maximum number of regulators in the smallest available cost effective package. Included in the IC are: One select-
able linear mode or switch mode charger; Four switching Buck converters for DC1/DC2/DC3/DC4, Three LDOs for
Image Signal Process and RTC applications, and Two Load Switch Enable Signal Control for Wi-Fi, DRAM applications.
For Charger part, when the input current limit or voltage limit is reached, the power path management automatically
reduces the charge current to zero. As the system load continues to increase, the power path discharges the battery
until the system power requirement is met. This supplement mode operation prevents overloading the input source.
The devices initiate and complete a charging cycle without software control. It automatically detects the battery voltage
and charges the battery in three phases: pre-conditioning, constant current and constant voltage. At the end of the
charging cycle, the charger automatically terminates when the charge current is below a preset limit in the constant
voltage phase. When the full battery falls below the recharge threshold, the charger will automatically start another
charging cycle.
The device provides various safety features for battery charging operation, including a pack negative thermistor
monitoring, charging safety timer and over-voltage/over-current protections.
For the other VRs, the IC is equipped with all the standard protection features such as current limit, over voltage and
internal under voltage lock out protection as well as thermal shutdown.
The serial interface is an I2C communication interface which allows supply sequencing as well as controlled margin-
ing of ramp up and ramp down of all supplies to optimize battery power consumption. The I2C interface also allows for
adjustability of VRsvoltage and Forced PWM Mode in default operation and Auto PSM/PWM Mode in OFF mode state.
Also, the power sequenc is defined by strobes and delay times under I2C Control.
The device is available in a 40-pin, 5x5 mm2 thin QFN package for best thermal performance while optimizing the cost.
