Description for the BQ24295

The bq24295 is a highly-integrated switch-mode battery charge management and system power path management devices for 1 cell Li-Ion and Li-polymer battery in a wide range of power bank, tablet and other portable device applications.

Its 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.

The device supports 3.9V – 6.2V USB input sources, including standard USB host port and USB charging port with 6.4V over-voltage protection. The bq24295 is compliant with USB 2.0 and USB 3.0 power specifications with input current and voltage regulation. To set the default input current limit, the bq24295 detects the input source through D+/D– detection following the USB battery charging spec 1.2. In addition, the bq24295 detects non-standard 2A/1A adapters. The bq24295 supports battery boost operation by supplying adjustable voltage 4.55 – 5.5V (default 5.1V) on PMID pin with minimum current of 1.5A.

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 supplement mode operation prevents overloading the input source.

The devices initiate and complete 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.

The devices provide various safety features for battery charging and system operation, including negative thermistor monitoring, charging safety timer and over-voltage/over-current 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 INT immediately notifies the host when a fault occurs.

The bq24295 is available in a 24-pin, 4×4 mm2 thin VQFN package.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

A custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships tube or tray devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
