BQ25898DYFFT 描述

***as Instruments: I2C 1cell 4A buck battery charger with power path and HVDCP 42-DSBGA -40 to 125

***ical: Switching Battery Charger Li-Ion/Li-Pol 4000mA 3.84V to 4.6V 42-Pin DSBGA T/R

***nell: BATT CHARGER, LI-ION/POL, 4A, DSBGA-42

***i-Key: IC BATT CHG LI-ION 1CELL 42DSBGA

***AS INSRUMENTS: The bq25898, bq25898D are highly-integrated 4-A switch-mode battery charge management and system power path management devices for single cell Li-Ion and Li-polymer battery. The devices support high input voltage fast charging.

***AS INSTRUMEN: The low impedance power path optimizes switch-mode operation efficiency, reduces battery charging time and extends battery life during discharging phase. The I2C Serial interface with charging and system settings makes the device a truly flexible solution.

***AS INTRUMENTS: The bq25898/98D is a highly-integrated 4-A 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 smartphone, tablet and portable devices. Its low impedance power path optimizes switch-mode operation efficiency, reduces battery charging time and extends battery life during discharging phase. It also integrates Input Current Optimizer (ICO) and Resistance Compensation (IRCOMP) to 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 and battery monitor for simplified system design. The I2C serial interface with charging and system settings makes the device a truly flexible solution.

***: The device supports a wide range of input sources, including standard USB host port, USB charging port, and USB compliant adjustable high voltage adapter. To support fast charging using adjustable high voltage adapter, the bq25898D provides support for MaxCharge™ handshake using D+/D- pins and DSEL pin for USB switch control. In addition, both bq25898D and bq25898 include interface to support adjustable high voltage adapter using input current pulse protocol. To set the default input current limit, device uses the built-in USB interface (bq25898D) or takes the result from detection circuit in the system (bq25898), such as USB PHY device. The device is compliant with USB 2.0 and USB 3.0 power spec with input current and voltage regulation. In addition, the Input Current Optimizer (ICO) supports the detection of maximum power point detection of the input source without overload. The device also meets USB On-the-Go (OTG) operation power rating specification by supplying 5 V (Adjustable 4.5V-5.5V) on VBUS with current limit up to 2.4 A.

***AS INSRUMENT: The power path management regulates the system slightly above battery voltage but does not drop below 3.5V 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 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 operation prevents overloading the input source.

***: The device initiates and completes a charging cycle without software control. It automatically detects the battery voltage and charges the battery in three phases: pre-conditioning, constant current and constant voltage. At the end of the charging cycle, the charger automatically terminates when the charge current is below a preset limit in the constant voltage phase. When the full battery falls below the recharge threshold, the charger will automatically start another charging cycle.

***AS INTRUMENTS: The charger provides various safety features for battery charging and system operations, including battery temperature negative thermistor monitoring, charging safety timer and overvoltage/overcurrent protections. The thermal regulation reduces charge current when the junction temperature exceeds 120°C (programmable). The STAT output reports the charging status and any fault conditions. The PG output (bq25898) indicates if a good power source is present. The INT immediately notifies host when fault occurs.

***: The device also provides a 7-bit analog-to-digital converter (ADC) for monitoring charge current and input/battery/system (VBUS, BAT, SYS, TS) voltages. The QON pin provides BATFET enable/reset control to exit low power ship mode or full system reset function.

***AS USD: The devices are available in a 42-ball, 2.8 mm x 2.5 mm DSBGA package.
