AOZ5473QE 80A High-Performance Smart Power Stage (SPS) General Description The AOZ5473QE is a high efficiency synchronous buck smart power stage module consisting of two asymmetrical MOSFETs and an integrated driver. The MOSFETs are individually optimized for operation in the synchronous buck configuration. The high-side MOSFET is optimized to achieve low capacitance and gate charge for fast switching with low duty cycle operation. The lowside MOSFET has ultra-low ON resistance to minimize conduction loss. Highly accurate current (IMON) and temperature (TMON) monitors are integrated in AOZ5473QE. AOS digital controllers, when used with AOZ5473QE, can digitize IMON and TMON to provide fault protection and telemetry via the digital communication bus.
