ITS711L1 Introduction

Many electrical applications frequently use integrated circuit power switches of the ITS711L1 type. The ITS711L1’s characteristics, applications, specifications, and the operating principle will all be covered in detail in this guide.


The N-channel power MOSFET ITS711L1 can function as a high-side or low-side switch. It has a 4.5V to 55V operating voltage range and a maximum continuous current handling capacity of 4A. The device is appropriate for high reliability and safety applications since it includes built-in thermal shutdown protection and overcurrent protection.

The ITS711L1 is contained in a surface-mount DSO-20 package with 20 pins. No additional components are needed for the device because it is built for simple installation on printed circuit boards (PCBs).


● EU RoHS Compliant: Yes

This shows that the ITS711L1 conforms with the Restriction of Hazardous Substances Directive of the European Union, which prohibits the use of specific hazardous materials in electrical and electronic equipment.

● ECCN (US): EAR99

The United States uses the Export Control Classification Number (ECCN) to identify goods that must comply with export control laws. The ITS711L1 is designated as EAR99, which denotes that it is a low-level technological item and doesn’t typically require an export license.

● Part Status: Unconfirmed

The part status reveals whether a component is in use, out of production, or still under development. In this instance, it is unclear whether the ITS711L1 is currently in production; hence, its unconfirmed status.

● Automotive: No

The Production Part Approval Procedure, or PPAP for short, is a standard used in the automotive industry to ensure that all of the components that go into the assembly of a vehicle are up to the necessary standards. In this instance, PPAP is not necessary for the ITS711L1 device.

● Number of Inputs: 4

This suggests that the ITS711L1 has four input channels that can control the switching of the output channels.

● Number of Outputs: 4

This suggests that the ITS711L1 has four output channels that can be activated or deactivated according to the signals sent.

● Maximum Output Current (A): 4.4 (Typical)

This number represents the maximum amount of current that the ITS711L1 can send across each output channel. The greatest amount of current that can be supplied to each individual output channel is typically 4.4 A.

● Minimum Input Voltage (V): 5

This identifies the minimum voltage that must be present at the input channels of the ITS711L1 to switch the output channels.

● Maximum Input Voltage (V): 34

This is the highest voltage that the ITS711L1 can withstand at the input channels without the component being damaged. This is the maximum voltage that the ITS711L1 can handle.

● Switch On Resistance (mOhm): 165

The component’s resistance during the output channels’ active state, or “on-state,” is represented by this value for the ITS711L1.

● Maximum Power Dissipation (mW): 3600

This value represents the maximum power the ITS711L1 can dissipate before the component suffers irreparable harm.


The ITS711L1 is a versatile power switch that can be used in various electrical applications. Here are a few examples of the many ways the ITS711L1 chip is usually used:

In the auto industry, it can be used: The ITS711L1 can be used in many different car parts, such as power windows, door locks, and sunroofs. Because the device prevents thermal shutdown and protects against overcurrent, it is perfect for use in these applications where safety is very important.

Industrial uses: The ITS711L1 can be used to control motors, solenoids, and power supplies, among other things, in a wide range of industrial settings. Because the device can handle high voltage and current, it is a great choice for these high-power applications.

Applications in consumer electronics: The ITS711L1 can also be used in consumer electronics like video game consoles, TVs, and home appliances. The part is perfect for use in the above portable electronic devices because it is small and easy to install.

Working Principle

The ITS711L1 is a power MOSFET switch that works in the linear part of its range of operation. The device acts like a variable resistor in the linear area, letting electricity flow through it. The gate voltage controls how much current can flow through the device.

When the gate voltage exceeds the threshold voltage, the circuit is in its “off” state, and no current can flow through it (Vth). When the gate voltage exceeds the threshold voltage, the device turns on, and current flows through it. When the gate voltage is higher than the threshold voltage, this happens. The gate voltage affects the amount of current that flows through the device in a way that is proportional to the amount of current.

As soon as the device is turned on, the drain-source voltage (Vds) across it drops to a very low value, and it starts to work in the saturation zone of its operating range. In the saturation zone, the part acts like a switch with very low resistance, letting a lot of current flow through it.

The device’s overcurrent protection kicks in when the current going through it are higher than the maximum current for which it was designed. When this happens, the device turns off. The “thermal shutdown prevention” function keeps the device from getting too hot. This makes sure that it works well and is safe.


In conclusion, the ITS711L1 power switch is a reliable and efficient device that can be used in various electronic applications. Its ability to handle high voltage and current, thermal shutdown prevention, and overcurrent protection features make it a safe choice for many applications. Its small size and easy installation make it ideal for compact electronic devices. Due to its high performance and dependability, the ITS711L1 is a popular component selected by electronic product manufacturers and designers.
