1. An integrated circuit comprising:
- a plurality of pins;
a first direct current to direct current converter arranged in a first selectable configuration corresponding to a selected battery mode determined in response to an input received at one of the plurality of pins; and
a second direct current to direct current converter arranged in a second selectable configuration based on the selected battery mode;
wherein the selected battery mode is selected from at least three different available battery modes and wherein when the selected battery mode is a first mode, the first selectable configuration is a first buck configuration and the second selectable configuration is a second buck configuration, and when the selected battery mode is a second mode, the first selectable configuration is the first buck configuration and the second selectable configuration is a boost configuration.

Abstract
A method and system to determine a battery mode of an integrated circuit device are presented. The battery mode is selected with respect to first and second direct current to direct current converter devices within the integrated circuit. A voltage is received at a single pin of the device. A battery mode is determined for the device based on the received voltage, and at least one of the direct current to direct current converter circuits is configured based on the determined battery mode.

16. A method of selecting a battery mode with respect to a first direct current to direct current converter circuit configuration and a second direct current to direct converter current circuit configuration within an integrated circuit, the method comprising:
-
receiving a voltage at a single pin of the integrated circuit; determining a battery mode based on the voltage received at the single pin, the battery mode selected from one of at least three different battery modes; and configuring at least one of the direct current to direct current converter circuit configurations based on the selected battery mode; placing the first direct current to direct current converter circuit in a first configuration; and placing the second direct current to direct current converter circuit in a second configuration; wherein the first and second configurations are selected based on the selected battery mode and wherein when the selected battery mode is a first mode, the first selectable configuration is a first buck configuration and the second selectable configuration is a second buck configuration, and when the selected battery mode is a second mode, the first selectable configuration is the first buck configuration and the second selectable configuration is a boost configuration. - View Dependent Claims (17, 18, 19, 20)
