Power management integrated circuits (PMICs) are integrated circuits that are designed to manage power in other circuits. PMICs are generally used in applications requiring multiple power supplies and/or higher levels of energy efficiency. Within PMICs, voltage references play a key role in providing a precise, stable reference voltage for use in regulating multiple supply rails simultaneously. The LM4050BIM3-4.1/NOPB is a voltage reference designed specifically to provide such a reference voltage.

The LM4050BIM3-4.1/NOPB is a CMOS voltage reference that provides 4.096V, with an output current capability of 2mA. It has extremely low temperature coefficient of only 0.0025mV/°C. This high stability, low temperature drift, and low power consumption make it an ideal choice for a wide range of applications. The device is triggered by application of a minimum input voltage of 1.5V, and features a preset accuracy of ±2.5mV.

The LM4050BIM3-4.1/NOPB is primarily used as a voltage reference in systems that require precise, stable voltages. It can be used to create precise bias levels, measure precise voltage levels, or to provide a precise reference voltage for analog-to-digital converters (ADCs), digital-to-analog converters (DACs) and other analog circuitry. Additionally, it can be used as a low-voltage protector, or as a low-voltage reset for microcontrollers or other digital logic.

When used as a voltage reference, the LM4050BIM3-4.1/NOPB first multiplies the applied reference input by a factor of one, creating a range of 0V to 4.096V. This range is then divided by a resistive divider network to create a precise 4.096V output. The resistive divider is made up of several very high impedance resistors that are calibrated to create an output voltage with a preset accuracy of ±2.5mV.

In addition to creating precise reference voltages, the LM4050BIM3-4.1/NOPB also provides good temperature stability. The temperature coefficient of the output voltage is less than 0.0025mV/°C and the device is able to maintain a stable output voltage over a temperature range from -40°C to 125°C. The device is also very low power, consuming only 150µA at a voltage of 4.096V.

The LM4050BIM3-4.1/NOPB is an excellent choice for a voltage reference in a wide range of applications. With its wide output voltage range, low temperature coefficient, high precision, and low power consumption, the device is ideal for creating a precise reference voltage for use in circuitry requiring stabilization or for other voltage reference related applications.
