This voltage VREF 10 could be used for ratiometric programming of voltage and current regulation. Charge voltage set reference input. Charge voltage set input. Valid adapter active-low detect logic open-drain output. Battery to system switch driver output. Gate drive for the battery to system load BAT PMOS power FET to isolate the system from the battery to prevent current flow from the system to the battery, while allowing a low impedance path from battery to system and while discharging the battery pack to the system load.

Connect the source of the FET to the system load voltage node. Connect the drain of the FET to the battery pack positive node.

An optional capacitor is placed from the gate to the source to slow down the switching times. The internal gate drive is asymmetrical to allow a quick turn-off and slower turn-on, in addition to the internal break-before-make logic with respect to ACDRV.

Adapter current sense amplifier output. Charge current set input. Battery voltage remote sense. Directly connect a kelvin sense trace from the battery pack positive terminal to the BAT BAT pin to accurately sense the battery pack voltage.

Place a 0.



Charge Enable pin, 5x5-mm QFN package? DESCRIPTION The bqA is a high-efficiency, synchronous battery charger with integrated compensation and system power selector logic, offering low component count for space-constrained multi-chemistry battery charging applications. Ratiometric charge current and voltage programming allows very high regulation accuracies, and can be either hardwired with resistors or programmed by the system power-management microcontroller using a DAC or GPIOs. Products conform to specifications per the terms of the Texas Instruments standard warranty. Production processing does not necessarily include testing of all parameters. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
