ALPHA & OMEGA SEMICONDUCTOR AOZ52383QI High-Current, High-Performance Smart Power Stage General Description The AOZ52383QI 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 AOZ52383QI provides an output current signal (IMON). The IMON signal can be directly used to replace inductor DCR sense or resistor sense in the multiphase voltage regulator system without any temperature compensation. The AOZ52383QI also includes an accurate module thermal monitor (TMON). TMON is a voltage sourced PTAT signal with 8 mV/°C. The MOSFETs are individually optimized for operation in the synchronous buck configuration.
