Abstract
Devices having battery charge control circuits are disclosed. Such devices can include power control circuits operable to receive electrical power at a connector, and provide power to electrical components, including a charge current for a rechargeable battery; and a controller circuit configured to determine and store a maximum charge current setting based on whether a voltage at the connector falls below a predetermined limit as the charge current is increased. Corresponding methods are also disclosed.
Claims20
An apparatus, comprising:
- power control circuits operable to receive electrical power at a connector, and provide power to electrical components, including a charge current for a rechargeable battery;
- and
- a controller circuit configured to determine and store a maximum charge current setting at which battery charging continues based on whether a voltage at the connector falls below a predetermined limit as the charge current is increased.
An apparatus, comprising:
- power control circuits operable to receive electrical power at a connector, and provide power to electrical components, including a charge current for a rechargeable battery;
- a controller circuit configured to determine and store a maximum charge current setting at which battery charging continues based on whether a voltage at the connector falls below a predetermined limit as the charge current is increased;
- and
- a device controller circuit configured to disable selected functions of the apparatus according to the maximum charge current settings.
