AAT4901 - Buffered Power Full-Bridge
Advanced Analogic Technologies 2008/08/06 15:17
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 components.
The AAT4901 is protected from shoot-through current by integrated break-before-make circuitry. The drivers can be independently controlled and their propagation 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 RDS(ON) and low quiescent current 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.
