Abstract
A switch control device includes a retention circuit configured to generate a trigger signal based on a fault signal indicating whether a fault indicated by a power signal occurred, generate a reset signal based on the trigger signal, store a present value of a driving signal at a time during a duration of an active edge of the trigger signal, and output the stored driving signal as a retention signal during a time duration of the reset signal; and a driving circuit configured to generate a switch control signal based on the retention signal and the driving signal, and output the switch control signal to a switch.
Claims20
A switch control device, comprising:
- a retention circuit configured to generate a trigger signal based on a fault signal indicating whether a fault indicated by a power signal occurred, generate a reset signal based on the trigger signal, store a driving signal during a time of an active edge of the trigger signal, and output the stored driving signal as a retention signal during a time duration of the reset signal;
- and
- a driving circuit configured to generate a switch control signal based on the retention signal and the driving signal and output the switch control signal to a switch.
A battery pack, comprising:
- a battery module comprising at least one cell;
- a switch connected between the battery module and a load;
- and
- a switch control device configured to turn the switch on or off using a switch control signal, the switch control device including:
- a retention circuit configured to generate a trigger signal based on a fault signal indicating whether a fault was indicated by a power signal, generate a reset signal based on the trigger signal, store a driving signal at a time during a duration of an active edge of the trigger signal, and output the stored driving signal as a retention signal during a time duration of the reset signal;
- and
- a driving circuit configured to generate a switch control signal based on the retention signal.
A switch control device, comprising:
- a retention circuit configured to output a retention signal;
- and
- a driving circuit configured to receive the retention signal and output a switch control signal;
- wherein
- a rise time of a trigger signal sets a duration of a reset signal, and a fall of the trigger signal causes a driving signal to be stored as a retention signal at a time during a duration of the fall of the trigger signal;
- and
- the retention signal is output to the driving circuit during the duration of the reset signal, and the trigger signal is based on a fault indicated by a power signal.
