Abstract
A battery-disconnect circuit may include a latch, a battery-disconnect subcircuit, and a power-enable subcircuit. The battery-disconnect subcircuit may be configured to control current leakage. The battery-disconnect subcircuit may be connected to the latch. The latch may be configured to maintain a power supply state of the battery-disconnect subcircuit, a no-power supply state of the battery-disconnect subcircuit, or both. The power-enable subcircuit may be connected to the battery-disconnect subcircuit. The power-enable subcircuit may be configured to switch the battery-disconnect subcircuit to the power supply state based on an enable signal. The power-enable subcircuit may be configured to switch the battery-disconnect subcircuit to the no-power supply state based on an off signal.
