Abstract

Battery charger circuitry includes a linear regulator and a current control loop. The linear regulator provides a constant current to a battery while the battery charger circuitry is in a current control mode. While the battery charger circuitry is in a constant voltage mode, the current control loop to: determine whether a charging current provided to the battery is less than an end of charging reference current; in response to the charging current being less than the end of charging reference current, to place the battery charger circuitry into an end of charging state; in response to the battery charger circuitry be placed the end of charging state, and to start a timer; and in response to the timer expiring, to enter the battery charger circuitry into a done state to end charging of the battery.
