PMIC (Power Management Integrated Circuit) has become an integral part of the present day electronic circuit interfaces, used for power management, voltage control and motor control. Voltage References are a part of the PMIC family and are used to compare and determine fixed reference values so as to control the output voltage. The TS4041DILT-1.2 (TS4041DILT) is one such voltage reference.

Application Field

The TS4041DILT offers an ideal solution for today’s voltage regulators, controllers, converters and high-current battery management. It is designed to provide a low-power, accurate and adjustable voltage reference source for microprocessors. It supports up to 6V/10A. The TS4041DILT-1.2 also offers excellent stability, accuracy and immune to temperature and noise. The wide range of input and output options allows the user to customize the voltage reference source to their exact specifications. Additionally, it has a low profile, allowing for easy and flexible integration into space-constrained applications.

Working Principle

TS4041DILT-1.2 operates on the open-loop principle of voltage regulation. This type of system works to maintain a constant output voltage despite changes in load, temperature, and other external conditions. This is accomplished by using an error amplifier to compare the output voltage to a reference voltage. If the output voltage is above the reference, the error amplifier will reduce the driver control signal, decreasing the output voltage. Conversely, if the output voltage is below the reference, the error amplifier will increase the driver control signal, raising the output voltage. In this way, the system will always strive towards achieving the desired reference voltage output.

The TS4041DILT voltage reference uses a combination of a high-accuracy operational amplifier and an analog to digital converter (ADC) to deliver the desired reference voltage. The operational amplifier is utilized to provide a stable output voltage that is proportional to the reference voltage, regardless of changes in external conditions. The analog section can be used for adjustments and fine-tuning of the output voltage. Finally, the ADC registers the output of the analog section and produces a digital output, allowing the user to accurately monitor and adjust the output voltage over a wide range of input/output conditions.

The TS4041DILT is also designed with a power governor to control the power flow and reduce energy consumption during operation. A low-power level detection circuit is used to initiate the power governor, enabling the device to intelligently switch to a lower power mode when the application’s power requirements decrease or if the input voltage is below the rated level. This feature eliminates the need for manual adjustment, allowing for precisely regulated and low-power operation even in low voltage conditions.

In conclusion, the TS4041DILT-1.2 is an excellent voltage reference, offering superior performance and accuracy. It is suitable for use in all types of voltage regulator, controller, converter and motor controller applications, allowing for compliance to a wide range of changing conditions. The low-power level detection and adjustable output voltage make it a great choice for applications with low-power requirements, while its low-profile design ensures easy and flexible integration into space-constrained systems.
