Introduction

MAX6129AEUK50+T is an application field and working principle for PMIC (Power Management Integrated circuit) - Voltage Reference. The device provides a small, accurate, and flexible low-power voltage reference for general-purpose applications such as microcontrollers, embedded systems, and analog control loops. It has an operating temperature range of -40°C to +85°C and is packaged in a 4 mm × 4 mm, 28-lead QFN package.

Functional Description

The MAX6129AEUK50+T provides a temperature-compensated, low-noise, highly accurate reference voltage. The reference source includes a bandgap output, a reference amplifier and an adjustable voltage reference. With a high accuracy of 0.6%, this voltage reference can be used in precision voltage references and isolated power supply applications. Its low quiescent current (1 μA typical) and low power dissipation (<25 μW typical) make it an ideal solution for battery-powered systems.The MAX6129AEUK50+T has two independent output pins. The reference output pin (VREF) provides an output voltage between 1.229 V and 4.25 V, with 5.25 mV adjustable increments. The VREF pin has a high accuracy of ±0.6% and a low temperature coefficient of <50ppm/°C.The MAX6129AEUK50+T also supports an adjustable output (VADJ) for easy reference voltage adjustment. The adjustment range is 1.0 V to 5.25 V and the accuracy is ±0.5%. The adjustment is accomplished by connecting a single resistor to the VADJ pin.

Applications

The MAX6129AEUK50+T is particularly suitable for precision power supply applications, low noise precision voltage reference, and analog control loops. It can be used in a variety of embedded systems such as medical, industrial, and telecom.The MAX6129AEUK50+T is also well-suited for measuring and trimming voltage references with built-in temperature compensation. It can also be used in a low-noise, low-power, two-resistor adjustable voltage references for other processes.

Conclusion

The MAX6129AEUK50+T is an ideal solution for low-power, low-noise, and low-temperature-coefficient voltage references. With its wide choice of operating voltage, adjustable voltage, and high accuracy, it is suitable for both general-purpose and precision voltage reference applications. The device’s small package size, wide temperature range, and low power consumption make it a great choice for battery-powered systems.
