Power Stages and Current Monitor Output Signal (IMON) Generation Circuit

Apparatus and associated methods relate to implementing an auto-inductance-detection architecture to reconstruct current monitor output (IMON) when a low-side switch in a power stage is on. In an illustrative example, an IMON generation circuit may include a variable resistor. A close loop control (e.g., OTA, switches, and variable resistor) may be configured to adjust a resistance value of the variable resistor automatically. The IMON generation circuit may also include a low pass filter coupled to a switching node of the power stage to receive a corresponding signal and provide a DC value. The difference between the corresponding signal and the DC value may be configured to enable or disable the close loop control. By providing the close loop control, the IMON generation circuit may advantageously perform auto-inductance detection (AID) and provide a more accurate IMON reconstruction method.
