The device is a 3.5 V, 6 A load switch in a 8-terminal SON package. To reduce voltage drop for low voltage and high current rails, the device implements an ultra-low resistance N-channel MOSFET which reduces the drop voltage when the load currents very high .

The device has a controlled, yet quick, fixed slew rate for applications that require quick turn-on response. During shutdown, the device has very low leakage currents, thereby reducing unnecessary leakages for downstream modules during standby. Integrated control logic, driver, and output discharge FET eliminates the need for any external components, which reduces solution size and BOM count.

Et3161 has high transmission efficiency due to its ultra-low RDS (on) and maximum 6A continuous current carrying capacity.

The device further reduces the total solution size by integrating a 240 Ω pull-down transistor for quick output discharge (QOD) when the switch is turned off.
