Methods and apparatus for dynamically adjusting an over-current protection threshold
Abstract:
Methods and apparatus for dynamically adjusting an over-current protection threshold (514) are disclosed. A dynamic over-current protection circuit (104) receives a first trigger to switch to a high discharge current mode. The dynamic over-current protection circuit (104) starts a high-current timer (210) and increases the over-current protection threshold (514) in response to receiving the trigger. The dynamic over-current protection circuit (104) decreases the over-current protection threshold (514) and starts a hold-off timer (212) in response to an expiration of the high current timer (210). The hold-off timer (212) prevents a second trigger from causing a switch to the high discharge current mode until the hold-off timer expires.
