Original Abstract Submitted

Implementations described herein relate to a power hold-off circuit and power hold-off circuit operation. In some implementations, a system may include a battery, and a power hold-off circuit. The power hold-off circuit may include a step-up regulator, a step-down regulator, a first abrupt power-loss (APL) switch, a second APL switch, and one or more power hold-off capacitors. The system may include a third APL switch between the battery and the power hold-off circuit. The third APL switch and the first APL switch may be in a closed state, and the second APL switch may be connected to the step-up regulator, when a voltage from the battery satisfies a voltage threshold. The third APL switch and the first APL switch may be in an open state, and the second APL switch may be connected to the step-down regulator, when the voltage from the battery does not satisfy the voltage threshold.
