Publication number: 20240143057Abstract: A voltage regulator system of an information handling system includes a Smart Power Stage (SPS) and a voltage regulator controller. The SPS includes a high-side transistor and a low-side transistor. The voltage regulator controller detects a normal power down of the information handling system and sets bleed state for the SPS to a first state. Based on the bleed state being set to the first state, the voltage regulator controller provides a first control voltage to the low-side transistor and a second control voltage to the high-side transistor. The first control voltage causes the low-side transistor to be fully turned on, and the second control voltage causes the high-side transistor to be in a linear region. In response to a predetermined amount of time expiring, the voltage regulator controller enters the SPS in an idle mode.Type: ApplicationFiled: October 26, 2022Publication date: May 2, 2024Inventors: James L. Petivan, III, Yun Guo, Isaac Q. Wang, Hang Li, Ronald Paul Rudiak, Justin Whittenberg

Patent number: 11599496Abstract: An information handling system includes an identification resistor, calibration circuitry, and a system-on-a-chip (SOC). The SOC sets the calibration line to a first digital state to place the calibration circuitry in an inventory mode. While the calibration circuitry is in the inventory mode, the SOC determines an inventory amount of time to charge the capacitor to a voltage substantially equal to a threshold voltage. The SOC then sets the calibration line to a second digital state to place the calibration circuitry in a calibration mode. While the calibration circuitry is in the calibration mode, the SOC determines a calibration amount of time to charge the capacitor to the voltage substantially equal to the threshold voltage. The SOC determines a resistance of the identification resistor based on the inventory amount of time and the calibration amount of time. The SOC also determines bit strapping information corresponding to the determined resistance.Type: GrantFiled: April 28, 2022Date of Patent: March 7, 2023Assignee: Dell Products L.P.Inventors: James L.
