Abstract
An electronic device has an energy storage device and circuitry supplied with a storage device voltage from the energy storage device. A supervisor circuit enables the circuitry in response to the storage device exceeding an enable threshold voltage. The supervisor circuit detects a resistance parameter which is indicative of an internal resistance of the energy storage device and adjusts the enable threshold voltage based on the resistance parameter.
