AAT4900 Buffered Power Half Bridge

The AAT4900 FastSwitch is a member of Skyworks' Application Specific Power MOSFET (ASPM™) product family. It is a buffered power half-bridge, consisting of low on resistance power MOSFETs with integrated control logic. This device operates with inputs ranging from 2.0V to 5.5V, making it ideal for 2.5V, 3V, and 5V systems. The device is protected from shoot-through current with its own control circuitry. The AAT4900 is capable of very fast switching times and is ideal for use in high frequency DC/DC converters. The quiescent supply current is a low 4mA at 1MHz CLK frequency. In shutdown mode, the supply current decreases to less than 1μA max. The AAT4900 is available in a Pb-free 5-pin SOT23 or 8-pin SC70JW package and is specified over the -40°C to +85°C temperature range.
