General Description

The CW6116EDAQ is a highly integrated 3A

switch mode battery charger with power path

management and reverse boost capability for

single-cell Li-Ion and Li-polymer battery. It features

fast charging with high input voltage support for a

wide range of smart phones, tablets and other

portable devices. Its low impedance power path

optimizes switch-mode operation efficiency,

reduces battery charging time and extends battery

life during discharging phase.

Its input voltage and current regulation deliver

maximum charging power to battery. The solution

is highly integrated with input reverse-blocking

FET (RBFET, Q1), high-side switching FET

(HSFET, Q2), low-side switching FET (LSFET, Q3),

and battery FET (BATFET, Q4) between system

and battery. It also integrates the bootstrap diode

for the high-side gate drive for simplified system

• Auto Detect USB BC1.2, SDP, CDP, DCP and

Non-standard Adaptors

High Battery Discharge Efficiency with 22.5mΩ

Battery Discharge MOSFET

Narrow Voltage DC (NVDC) Power Path

Management

• Instant-On Works with No Battery or Deeply

Discharged Battery



• Ideal Diode Operation in Battery Supplement

Mode



Ship Mode, Wake-Up and Full System Reset

Capability by Battery FET Control

Flexible Autonomous and I²C Operation Modes

for Optimal System Performance

Fully Integrated Switches, Current Sense and

Compensation



19µA Ship Mode Low Battery Leakage Current

High Accuracy
