ETA6964

13.5V/3A, 1-Cell Battery Charger with Power Path Management

DESCRIPTION

FEATURES

ETA6964 is a highly-integrated 3A switch-mode battery

charge management and system power path management

device 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 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 (Q1), high-side switching FET (Q2),

low-side switching FET (Q3), and battery FET (Q4) between

system and battery. It also integrates the bootstrap diode for

the high-side gate drive for simplified system design. The

device supports a wide range of input sources: standard

USB host port, USB charging port, and USB compliant high

voltage adapter. To support fast charging using high voltage

adapter. The device is compliant with USB 2.0 and USB 3.0

power spec with input current and voltage regulation. The

device also meets USB On-the-Go (OTG) operation power

rating specification by supplying 5.15 V on BUS with

constant current limit up to 1.2A.

 High-Efficiency, 1.5MHz Synchronous Switching Buck

Charger



 Wide Range Single Input to Support both USB Input and

High Voltage Adapters



Support 3.9V to 13.5V Input Voltage Range with

22V Absolute Maximum Input Voltage Rating

Maximum Power Tracking by Input Voltage Limit Up

to 4.5V (V_INDPM

)

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

and Non-Standard Adaptors

 High Battery Discharge Efficiency with 27mΩ Battery

Discharge MOSFET

 Fast Turn-Off of Operational External OVPFET, Standing

Input Voltage Up to 40V

 Narrow VDC (NVDC) Power Path Management

 High Integration Includes All MOSFETs, Current Sensing

and Loop Compensation

The power path management regulates the system slightly

above battery voltage but does not drop below 3.5 V

minimum system voltage. With this feature, the system

maintains operation even when the battery is completely

depleted or removed. 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 prevents overloading the input source.

ETA6964 also integrates an input OVP controller to protect

itself from an input voltage surge as high as 40V.

 Safety



Battery Temperature Sensing for Charge and Boost

Mode



Thermal Regulation and Thermal Shutdown

 Input UVLO and Overvoltage Protection

 Available in a QFN4x4-24 package
