PMIC stands for Power Management Integrated Circuit, which senses, monitors, and controls the power associated with digital and analog systems. Voltage References are an important type of PMIC, used to provide a reference voltage on an integrated circuit with an output that remains constant regardless of variations in external circuitry. The LM4130BIM5X-2.5 is an example of a Voltage Reference PMIC.

Application Field

The LM4130BIM5X-2.5 is designed for applications such as bistable memory circuits where the minimum supply voltage is greater than 2.6V. It also has a wide voltage range for low current consumption, making it ideal for portable applications where extended battery life is required. Some applications that this specific PMIC can be used for include building stable reference voltages for logic circuits, data acquisition, sensing and monitoring systems, mobile phones, portable navigation systems and more. In addition, the LM4130BIM5X-2.5 features short-circuit protection as well as operational amplifier selectable rail-to-rail output range.

Working Principle

The LM4130BIM5X-2.5 is a precision Voltage Reference PMIC capable of providing accurate references in any application. It has a reference voltage output of 2.5Vdc with a typical temperature coefficient of 5ppm/°C. The reference voltage is set by pulling either the ADJ or the TEMP pin to one of the several scaled reference voltages. This configures the reference voltage and sets the output accordingly. The control circuitry of thePMIC then maintains the output voltage of theLM4130BIM5X-2.5 by using an internal band-gap to sense any changes in the output voltage and then adjust the current flow to the output pin accordingly.

Conclusion

The LM4130BIM5X-2.5 is an excellent Voltage Reference PMIC that can be used in a wide variety of applications requiring an adjustable reference voltage. It features a reference voltage output of 2.5Vdc with a typical temperature coefficient of 5ppm/°C and has operational amplifier input and output selectable range. The control circuitry of the PMIC handles short-circuit protection and maintains its output voltage by sensing changes and adjusting the current flow accordingly.
