AOZ52183QI - Smart Power Stage

Datasheet Summary

Description

The AOZ52183QI is a general-purpose Smart Power Stage (SPS) consisting of two asymmetrical MOSFETs and an integrated driver for high current, high frequency DC-DC converters.

The AOZ52183QI provides an output current signal (IMON), which reports the real-time module current with a gain of 5 mV/A.

Features

  • 3 V to 25 V power supply range.
  • 45 A continuous output current - Up to 65 A for 20 ms instantaneous current @ 14 V VIN - Up to 60 A for 20 ms instantaneous current @ 22 V VIN - Up to 80 A for 10 us instantaneous current.
  • Optimized for switching frequency up to 1.5 MHz.
  • Integrated current monitor (5 mV/A) with typical 3% accuracy over temperature.
  • Integrated temperature monitor (8 mV/ oC) with 2% accuracy.
  • Fault Indicator.
  • Under-Volt.

AOZ52183QI High-Current, High-Performance Smart Power Stage for Notebook CPU Power General Description The AOZ52183QI is a general-purpose Smart Power Stage (SPS) consisting of two asymmetrical MOSFETs and an integrated driver for high current, high frequency DC-DC converters. The AOZ52183QI provides an output current signal (IMON), which reports the real-time module current with a gain of 5 mV/A. The IMON signal can be directly used to replace inductor DCR sensing or resistor sensing in multiphase voltage regulator systems without the need for temperature compensation. The AOZ52183QI also includes an accurate module temperature monitor (TMON). TMON is a voltage sourced signal with a gain of 8 mV/oC.
