AOZ52178QI Description
The AOZ52178QI 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 AOZ52178QI 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...
