AAT4901 Buffered Power Half Bridge

The AAT4901 FastSwitch™ is a member of Skyworks' 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 includes thermal protection to safeguard the device under extreme operating conditions. 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.
