POWER HOLD-OFF CIRCUIT

This abstract first appeared for US patent application 20250140293 titled 'POWER HOLD-OFF CIRCUIT

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.
