The ICL7631CCSE is a monolithic CMOS integrated circuit that serves as a voltage controlled current source (VCCS) or current controlled current source (CCCS) depending on how it is configured. It provides a high degree of accuracy and stability under varying environmental conditions and is used in a number of applications. This article will discuss the application field and working principle of the ICL7631CCSE.

Application Field

The ICL7631CCSE can be used in a range of applications, ranging from sensing current, to measuring power, and temperature. It is often used to control small devices such as motors, thermocouples, and pressure transducers. It can also be used in power supplies and in active filters.

The ICL7631CCSE is also commonly used in medical and laboratory instrumentation, providing accurate and reliable current control. Its application range has also been extended to automotive applications such as fuel injectors and engine management systems. It is becoming increasingly popular in the field of robotics, where it can be used to regulate various types of actuators.

The ICL7631CCSE is also suitable for powering remote components, as its output current is accurately controllable and its operating temperature range is relatively tolerant. With reprogrammable control settings, it can be used to power LEDs, vibrators, motors, and other low-voltage devices.

Working Principle

The ICL7631CCSE operates on a voltage-to-current conversion principle. It is supplied with a positive voltage from an external power source, and its output current is dependent on the potential difference between its input and feedback terminals—essentially a voltage difference multiplied by several fixed factors. It is capable of outputting both positive and negative current.

The ICL7631CCSE’s output current is determined by the input voltage, and its output resistance is determined by the circuit’s current limiting element. In most configurations, this current limiting element is connected to the output through a resistor, and the current limiting element’s value determines the amount of current that is allowed to pass through the output. As the voltage across the current limiting element exceeds its maximum rating, the current through the output channels is limited, and decreasing further.

The ICL7631CCSE is also capable of supplying very low output current. This makes it ideal for controlling small loads, such as micro-actuators, relays and low-power LEDs. The ICL7631CCSE can operate over a wide temperature range, and its output current can be adjusted through external feedback, making it suitable for a wide range of control applications.

Conclusion

The ICL7631CCSE is a versatile CMOS integrated circuit suitable for a range of applications. Its voltage-to-current conversion principle allows it to provide accurate and reliable current control. It can be used in a number of devices, such as medical and laboratory equipment, power supplies, automotive systems, robotics and remote components. Its wide operating temperature range and reprogrammable control settings make it a reliable and desirable component for many applications.
