RT5016C
I2C Programmable Multi-Channel PMU with Battery Charger
for CMOS DSC/DV
General Description
The RT5016C is a complete power supply solution for
digital still cameras and other hand held devices. The
RT5016C is composed of a multi-channel DC/DC power
converter unit, a single-cell linear Li-ion battery charger, a
charger type detector, and an I2C control interface.
The power converter unit includes one synchronous step-
up converter (CH1), one synchronous step-up/down
converter (CH2), three synchronous step-down converters
(CH3/4/5), two LDOs with input power as low as 1.5V
(CH6/8), one WLED driver in synchronous high-voltage
step-up mode or low-voltage current regulator mode (CH7),
and a keep-alive LDO (CH9) for RTC application. All
converters are internally frequency compensated and
integrate power MOSFETs. The power converter unit
provides complete protection functions : over-current,
thermal shutdown, over-voltage, and under-voltage
protection. The RT5016C has a WAKEUP impulse
generation circuitry to monitor VIN or BAT installation
event. To fulfill most of applications, the RT5016C has six
preset power-on/off sequences.
The battery charger includes Auto Power Path
Management (APPM). No external MOSFETs are required.
The charger can enter sleep mode when power is removed.
Charging tasks are optimized by using a control algorithm
to vary the charge rate, including pre-charge mode, fast
charge mode and constant voltage mode. The charge
current can also be programmed via the I2C control
interface. The battery regulation voltage and current can
be adjusted by JEITA standard temperature control or other
schemes set via the I2C interface. The internal thermal
feedback circuitry regulates the die temperature to optimize
the charge rate for all ambient temperatures. The charging
task will always be terminated in constant-voltage mode
when the charging current reduces to the termination
current of 10% x ICHG_FAST. The charger includes under-
voltage and over-voltage protection for the supply input
voltage, VIN. The charger includes USB charger detection
circuitry via D+ and D- pins of USB interface to detect
USB standard downstream ports (SDP), USB charging
downstream port (CDP), dedicated charger port (DCP),
or Apple/Sony charger ports. RT5016C uses some
indicators to show charger states : two open drain ports
CHG and CHG2, and an interrupt (INT) to immediately notify
the state change.
The RT5016C has I2C interface to control rich functions of
Power Converter Unit and Charger Unit, and is available in
the WQFN-40L 5x5 package.
