These devices offer a constant-frequency synchronous switching pulse-width modulation (PWM) controller with highly accurate charge current and voltage regulation, charge preconditioning, termination, adapter current regulation and charge status monitoring. The battery is charged in three phases: preconditioning, constant current and constant voltage. A programmable charge timer provides a safety backup.
Key features and benefits
· Higher efficiency results in less heat dissipation than other solutions.
· Greater than 99 percent charge voltage and current accuracy optimize battery life cycle.
· Integrated, standalone solution enhances design flexibility and reduces overall solution size.
· Dynamic power management maximizes use of adapter power to power the system while charging the battery.
