AAT4900 Buffered Power Half-Bridge General Description The AAT4900 FastSwitchä is a member of AnalogicTech’s Application Specific Power MOSFETä (ASPMä) product family. It is a Buffered Power Half-Bridge, consisting of low onresistance Power MOSFETs with integrated control logic. This device operates with inputs ranging from 2.7V to 5.5V, making it ideal for both 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 to DC Converters. The quiescent supply current is a low 1mA (max) at 1MHz CLK frequency. In shutdown mode, the supply current decreases to 1µA max The AAT4900 is available in 5 pin SOT-23 specified over -40 to 85°C.
