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.

Charger for Battery

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 I

2C control

interface. The battery regulation voltage and current can

be adjusted by JEITA standard temperature control or other

schemes set via the I

2C 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), 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.
