The PI3L301DAEX is a USB Type-C Crossbar,configurable Single-Pole/Single-Throw (SPST) analog switch with a low On-Resistance. It is designed to switch signals in a range from 2.5V to 6V with protection from both short-term and long-term over-currents, short-circuits, and load dumps. The PI3L301DAEX is available in both through-hole and surface-mount packages.

Application Field

The applications related to the PI3L301DAEX are found nearly everywhere due to the versatility of analog switches. The PI3L301DAEX can be used as a low On-Resistance switch to control access to memory, as a touch sensing switch with protection against load dumps, to switch between portable device displays, or as part of a USB Type-C interfacing and control circuit.

The main application field is USB Type-C, a symmetrical interface standard for modern electronic products. It containing 24 power and ground pins, plus optional side-band signals for interference reduction, and is commonly found on laptops, cell phones, gaming consoles, cameras, and even automotive electronics. The ability to switch between different power supplies and to control current flow helps to ensure the correct connections in USB Type-C devices.

The PI3L301DAEX is well-suited for a broad range of applications. It can be used in audio amplification systems, automotive applications such as ECU control and in-car diagnostics, medical equipment such as imaging and diagnostics, wireless communications, green energy applications, and in power and control circuits.

Working Principle

The PI3L301DAEX is a SPST analog switch with protection from over-currents, short-circuits, and load dumps. The switch contains two terminals, which are connected through an internal N-channel MOSFET with an On-Resistance of 8 mΩ. The switch is designed to handle signal voltages between 2.5V and 6V.

The PI3L301DAEX is a control signal switch. When the signal voltage to the control port is between 0V and 0.2V, the channel is open, while a voltage greater than 3V will close the switch. The low On-Resistance of the PI3L301DAEX allows signals to pass quickly through it, while providing protection against over-currents and short-circuits.

The PI3L301DAEX also contains protection against load dumps, making it a practical choice for demanding applications. Load dumps occur when a voltage is suddenly removed from a device, usually due to power supply failure. The PI3L301DAEX helps to ensure that the surge of current is limited and will not cause a device to be shut down due to a power failure.

The PI3L301DAEX is a versatile switch, with a range of applications in the automotive, audio, medical, power, and control industries. Its low On-Resistance and protection from over-currents, short-circuits, and load dumps make it a reliable and robust choice for a range of complex applications.
