MAX6129BEUK21+T is a voltage reference module that belongs to the PMIC (Power Management IC) family. It is intended for use in applications such as battery monitoring, voltage regulation, power supply voltage control, and other systems where accurate voltage referencing is required. It features low quiescent current, very good temperature performance, and high accuracy.

The MAX6129BEUK21+T module has two channels and one dedicated temperature transfer pin. The two channels serve different voltage ranges and have different temperature coefficients. The first channel targets 1.25-10V operating range with 0.8ppm/K temperature coefficient, while the second channel targets 2.5-20V operating range with 1.5ppm/K temperature coefficient.

The architecture of MAX6129BEUK21+T is based on a low quiescent current reference circuit. This is realized by a simple two-resistor voltage divider with a 5-decade linear gain. The output of the two channels is steered by two temperature-strong transistors, operating in either linear or logarithmic modes. The temperature transfer pin allows the gaining and temperature coefficient of the two channels to be matched. The module also includes a 500μA current-limit resistor.

The MAX6129BEUK21+T voltage reference module is ideal for low power consumption applications. Its low quiescent current and robust temperature performance makes it an excellent choice for systems where accurate voltage references are desired. Furthermore, its dual-channel architecture allows for linear and logarithmic operation for increased output voltage accuracy. As such, it is a popular choice for voltage reference solutions.
