Introduction to TPS79718MDCKREP Application Field and Working Principle

TPS79718MDCKREP is a Linear Voltage Regulator (LVR) with integrated Battery Backup circuit. This IC provides a highly accurate output voltage, as well as a wide range of operating temperature. It is designed to provide stable output voltage even under heavy load and can support both fixed and adjustable output voltage.

The TPS79718MDCKREP is ideal for a variety of industrial and commercial applications, where an ultra-low quiescent current and a low drain on the battery are required. These applications include motor control, medical devices, industrial process control, automotive, communications, and telecommunications.

Working Principle

The TPS79718MDCKREP follows a conventional LVR configuration, where a single regulator is employed for both input and output voltage regulation. When power is applied, the integrated switching and feedback loop are designed to maintain a regulated output voltage. The output voltage is regulated by the integrated error amplifier, which compares the REFP voltage to the FB pin voltage. If the voltage at the FB pin is lower than the REFP voltage, the error amplifier will turn on the pass device and allow more current to flow through the circuit. Conversely, if the voltage at the FB pin is higher than the REFP voltage, the error amplifier will turn off the pass device, reducing the current passing through the circuit.

The TPS79718MDCKREP includes two integral multiplexers; one for the FB pin and the other for the REFP pin. The multiplexers are used to enable the user to select one of two input signals for the respective pins. This allows for either a fixed voltage setting or for a voltage setting to be set using an external voltage reference or program voltage.

Application Areas

The TPS79718MDCKREP is most commonly used in motor control, medical devices, industrial process control, automotive, communications, and telecommunications. In motor control applications, the IC can be used to provide a regulated supply voltage that is adequate to drive a wide range of motors, including BLDC and SR motors. The IC is also used in medical devices such as patient monitors, anesthesia machines and other medical equipment.

The TPS79718MDCKREP is also used in industrial process control, to provide a regulated supply voltage to a variety of sensors, displays, and controllers. It can also be used to provide a reliable power source in communications and telecommunication systems, providing a low power standby mode when not in use. Finally, the IC can be used in automotive applications, as it is designed to operate in wide temperature ranges, meaning it can be used for in-vehicle applications.

Conclusion

In conclusion, the TPS79718MDCKREP is an ideal solution for a variety of industrial and commercial applications, where an ultra-low quiescent current and a low drain on the battery are required. This IC provides a highly accurate output voltage and is designed to handle both fixed and adjustable output voltage. The integrated battery backup circuit enables the device to keep the regulated voltage on even when external power is lost, meaning that the device will remain powered even in the event of a power outage. This makes the TPS79718MDCKREP an ideal solution for applications requiring a reliable source of voltage.
