AAT4901 Datasheet, PDF (1/16 Pages) Advanced Analogic Technologies – Buffered Power Full-Bridge

FastSwitch^TM
General Description
The AAT4901 FastSwitch™ is a member of AnalogicTech’s
Application Specific Power MOSFET™ (ASPM™) product
family. It is a full-bridge buffered power stage operating
with an input voltage range of 2.0V to 5.5V. The device
is designed to operate with a switching frequency of up
to 2MHz, minimizing the cost and size of external com-
ponents. The AAT4901 is protected from shoot-through
current by integrated break-before-make circuitry. The
drivers can be independently controlled and their propa-
gation delay, from input to output, is typically between
8ns-19ns dependent upon logic option.
Four options are offered providing a single input control,
dual input control or as two independent half-bridges.
Other features include low R_DS(ON) and low quiescent cur-
rent allowing for high efficiency performance.
The AAT4901 is available in the space-saving, Pb-free
8-pin SC70JW package and is rated over the -40°C to
+85°C temperature range.
