It takes 5V USB input source to charge a dual cell battery with boost configuration in three phases: preconditioning, constant current, and constant voltage. Charge is terminated when the current reaches 10% of the fast charge rate. The battery charger is thermally regulated at 110˚C with charge current foldback. If input 5V is not present, ACT2804 discharge a dual cell battery with buck configuration to provide 5.07V+/-1% to output ports. There is a power path from input to output. The cycle-by-cycle peak current mode control, constant current regulation, short circuit protection and over voltage protection maximize safe operation. ACT2804 provides 4 LED drive pins for battery capacity level and charge status indication to indicate 25%, 50%, 75%, and 75% above battery level with battery impedance compensation. The LED indication patterns are programmable . ACT2804 is available in a thermally enhanced 5mmx5mm QFN55-40 package with exposed pad. 5V/3.4A Dual Cell Battery Power Manager Rev 3, Apr-17-2017 ACT2804 Buck Output CC/CV 6.0 5.0 4.0 3.0 2.0 1.0 0 Output Current (mA) 0 500 1000 1500 2000 2500 3000 VBAT = 8.2V VBAT = 6.0V 1A Output 2.4A Output |
