New from AnalogicTech is the AAT4282A, a device that allows designers to reduce parts count and cost by integrating two low resistance, slew rate controlled load switches in a single 2 x 2 mm package. It features two MOSFETs, each with a typical RDS(ON) of just 60 mΩ at 5 V, to support high load switch current handling capacity with a low forward voltage drop.
Designed for high side load switching applications, the AAT4282A supports both 3 V and 5 V systems by operating from a wide 1,5 V to 6,5 V input range. Quiescent current is a low 1 μA and input logic levels are both TTL and 2,5 V to 5 V CMOS compatible.
The module is available in three versions with different turn-on and turn-off characteristics. For high speed switching applications, it offers turn-on capabilities of less than 500 ns and turn-off capabilities of less than 3 μs typical. Also featured are a minimised slew rate limited turn-on function and a shutdown output discharge circuit to rapidly turn off a load when the switch is disabled.
The AAT4282A also features a slew-rate selector pin which allows the designer to switch between fast and slow slew rates on the same device. It is qualified across the -40°C to +85°C temperature range, and is available in a Pb-free, 8-pin FTDFN22-8 package.
