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. A dual

functionality TMON/FLT pin reports temperature

information during normal operating conditions and also

reports OC, OT, HS-short, LS-short faults. When a fault is

detected, the TMON/FLT pin is pulled high.

Dual-layer OC Protection includes a fixed 80 A detection

level which enable an OC fault flag and a 100 A cycle-bycycle

current limit. This second-level protection turns off

the high-side MOSFET, disabling the output. The

AOZ5473QE protection also includes thermal shutdown.

The bootstrap switch, with auto boot refresh feature, is

integrated into the driver. The low-side MOSFET can be

driven into diode emulation mode to provide

asynchronous operation when required. The pin-out is

optimized for low inductance routing of the converter,

keeping the parasitic effects to a minimum.
