BQ25302RTER General Description
The BQ25302 is a highly-integrated standalone switch-mode battery charger for single cell Li-Ion and Li-polymer batteries. The BQ25302 supports 4.1-V to 6.2-V input voltage and 2-A fast charge. The integrated current sensing topology of the device enables high charge efficiency and low BOM cost. The best-in-class 200-nA low quiescent current of the device conserves battery energy and maximizes the shelf time for portable devices. The BQ25302 is available in a 3x3 WQFN package for easy 2-layer layout and space limited applications.
The BQ25302supports 4.1-V to 6.2-V input to charge single cell batteries. The BQ25302 provides up to 2-A continuous fast charge current to a single cell battery. The device features fast charging for portable devices. Its input voltage regulation delivers maximum charging power to the battery from input source. The solution is highly integrated with an input reverse-blocking FET (RBFET, Q1), high-side switching FET (HSFET, Q2), and low-side switching FET (LSFET, Q3).
The BQ25302 features lossless integrated current sensing to reduce power loss and BOM cost with minimized component count. It also integrates a bootstrap diode for the high-side gate drive and battery temperature monitor to simplify system design. The device initiates and completes a charging cycle without host control. The BQ25302 charge voltage and charge current are set by external resistors. The BQ25302detects the charge voltage setting at startup and charges the battery in four phases: battery short, pre-conditioning, constant current, and constant voltage. At the end of the charging cycle, the charger automatically terminates if the charge current is below the termination current threshold and the battery voltage is above the recharge threshold. When the battery voltage falls below the recharge threshold, the charger will automatically start another charging cycle. The charger provides various safety features for battery charging and system operations, including battery temperature monitoring based on negative temperature coefficient (NTC) thermistor, charge safety timer, input over-voltage and over-current protections, as well as battery over-voltage protection. Pin open and short protection is also built in to protect against the charge current setting pin ICHG accidently open or short to GND. The thermal regulation regulates charge current to limit die temperature during high power operation or high ambient temperature conditions.
The STAT pin output reports charging status and fault conditions. When the input voltage is removed, the device automatically enters HiZ mode with very low leakage current from battery to the charger device. The BQ25302 is available in a 3 mm x 3 mm thin WQFN package.
