    Abstract: Methods and apparatus for converting power using a multi-output switched- mode power supply (SMPS) coupled to a multi-cell-in-series battery, such as charging a two-cell-in-series (2S) battery using a dual-output three-level buck converter coupled thereto, or using a multi-input SMPS circuit receiving power from a multi-cell-in-series battery. One example power supply circuit generally includes a switched-mode power supply circuit having an input node and an output node, a battery comprising multiple cells connected in series, a charge pump circuit having a first terminal and a second terminal, the second terminal of the charge pump circuit being coupled to the battery, a first switch coupled between the output node of the switched-mode power supply circuit and the first terminal of the charge pump circuit, and a second switch coupled between the output node of the switched-mode power supply circuit and the second terminal of the charge pump circuit.

    Abstract: A method, an apparatus, and a computer program product for booting the apparatus with a low-energy battery are provided. In a first configuration, the apparatus monitors a level of the battery while the battery is charging. The apparatus attempts a boot of the apparatus when the level is greater than or equal to a dynamic boot threshold. The apparatus increases the dynamic boot threshold when the boot is unsuccessful and repeating the monitoring and the attempting based on the increased dynamic boot threshold. In a second configuration, the apparatus detects a connection to an external power source. The apparatus attempts a boot using an FLCB protocol that is based upon power drawn directly from the external power source upon detecting the connection to the external power source. The apparatus attempts the boot as part of an ATC protocol when the boot using the FLCB protocol is unsuccessful.

    Abstract: A method, apparatus, and non-transitory computer readable medium are provided for high current battery charging using IR dropout compensation. The method first measures a battery current value and then multiplies that battery current value by an effective resistance of the battery to produce an effective dropout voltage value. The effective battery voltage value is then compared with a desired battery top off voltage value. The switch mode battery charger output setpoint is adjusted based on the setpoint voltage. Battery current and terminal current are then compared. Charging is terminated if the battery current is less than the terminal current. If the battery current is greater than the terminal current the battery current value is measured again and the charging process continues until the condition is met.
