 ETA6953Q4Y

ETA6953Q4Y’s General Description 

The ETA6953 is a highly-integrated 3.0-A switch-mode battery charge management and system power path management device for single cell Li-on 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 (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 design. The I2C serial interface with charging and system settings makes the device a truly flexible solution.（ 点击即可咨询芯片详细信息）

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 ETA6953 provides PSEL pin for USB switch control, To set the default input current limit, device takes the result from detection circuit in the system, such as USB PHY device The device is compliant with USB 2.0 and USB3.0 power specwith input current and voltage regulation. The device also meets USB On-the-Go(OTG) operation power rating specification by supplying 5.15 V on VBUS with constant current limit up to 1.2-A.

The power path management regulates the system slightly above battery voltage but does not drop below 3.5 V minimum system voltage (programmable), With this feature, the system maintains operation even when the battery is completely depleted or removed. When the input current limit orvoltage limit is reached, the powerpath 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.

The ETA6953 is available in a QFN4x4-24L package
