Power Switching Circuitry with Feedback Control - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240097672 titled 'Power Switching Circuitry with Feedback Control
Simplified Explanation
The integrated circuit described in the patent application includes power switching circuitry with a primary power switch and multiple auxiliary power switches. A power gating control circuit outputs control signals to activate the primary power switch and at least one auxiliary power switch to charge a gated voltage. Voltage detectors monitor the gated voltage and activate the remaining auxiliary power switches when the voltage exceeds certain thresholds. This configuration provides inrush current surge protection while charging the gated voltage quickly.
- Primary power switch and multiple auxiliary power switches
- Power gating control circuit for activating switches

Original Abstract Submitted
an integrated circuit may be provided with power switching circuitry. the power switching circuitry may include a primary power switch and multiple auxiliary power switches. a power gating control circuit may output control signals for selectively activating the primary power switch and at least one of the auxiliary power switches to charge a gated voltage. one or more voltage detectors may be configured to monitor the gated voltage and to activate the remaining auxiliary power switches in response to detecting that the gated voltage exceeds one or more thresholds. configured and operated in this way, inrush current surge protection can be achieved while charging up the gated voltage sufficiently fast.
