ALPHA & OMEGA SEMICONDUCTOR AOZ52371QI High-Current, High-Performance Smart Power Stage General Description The AOZ52371QI is a general-purpose Smart Power Stage (SPS) for computing notebook CPU power, consisting of two asymmetrical MOSFETs and an integrated driver for high current, high frequency, and DC-DC converter. The AOZ52371QI provides an output current signal (IMON). The IMON signal can be directly used to replace inductor DCR sensing or resistor sensing in the multiphase voltage regulator systems without the need for temperature compensation. The AOZ52371QI also includes an accurate module thermal monitor (TMON). TMON is a voltage sourced PTAT signal with a gain of 8 mV/°C. The MOSFETs are individually optimized for operation in the synchronous buck configuration.
