Power management integrated circuit (PMIC) is a highly integrated device that provides power management functions, typically with adjustable and regulated voltage supplies, high voltage and low voltage power control, multiple power outputs and bidirectional current flow. PMICs can provide maximum efficiency and reliability with their adjustable and regulated voltage supply technology. The LM4121IM5-ADJ/NOPB is a high-performance PMIC voltage reference module, primarily designed for automotive and industrial applications. It offers a wide range of features, including adjustable voltage reference, regulated voltage outputs, variable current limiting, and integrated temperature sensing.

Application Field and Working Principle

The LM4121IM5-ADJ/NOPB application field covers most areas where a stable voltage reference is required. It is particularly suitable for automotive and industrial applications, such as automotive engine control, battery control, power supply systems, and industrial control. The device is also suitable for use in systems or applications such as automotive navigation, navigation computer control, navigation GPS systems, navigation POI systems, road navigation systems, and speed control systems.

The LM4121IM5-ADJ/NOPB PMIC voltage reference module operates as a differential voltage reference that provides a stable voltage reference, adjustable over a wide range of output voltages. It also provides adjustable current limiting, over-voltage and over temperature protection, and protection from reversed polarity input voltage and output voltage. The device features an integrated temperature sensor, adjustable voltage control, voltage feedback and voltage regulation.

The core of the LM4121IM5-ADJ/NOPB PMIC is its voltage reference, which is typically powered with a supply voltage of 5 V. The output of the voltage reference is then filtered and amplified with other high-performance integrated circuits, such as an op-amp and a voltage follower. This provides stable voltage outputs which remain constant over a wide range of operating temperatures and supply voltages.

The LM4121IM5-ADJ/NOPB PMIC provides several methods of the adjustable output voltage. It is capable of adjusting the output voltage in two ways: via the adjust pin, and by adjusting the feedback voltage. The adjust pin can be used to adjust the output voltage over a range of 1V to 7V, and the feedback voltage can be used to adjust the output voltage over a range of 1V to 8V.

The LM4121IM5-ADJ/NOPB also provides adjustable current limiting. The current limit is adjustable over the range of 0.1A to 3A, with the maximum current limit being determined by the selected output voltage range. This makes the device suitable for a wide range of applications, from low-power automotive applications to high-power industrial applications.

The device also features an integrated temperature sensor which can be used to detect changes in voltage levels and power supply conditions. The integrated temperature sensor monitors the internal junction temperature of the device, and will shut down the output voltage if it exceeds a predetermined temperature limit.

The LM4121IM5-ADJ/NOPB is designed to provide excellent line and load regulation, with a minimum of 1.8% droop at full load. This ensures that the output voltage remains consistent and stable under a wide range of operating conditions.

The LM4121IM5-ADJ/NOPB is a high-performance PMIC voltage reference module, designed to provide reliable and stable voltage reference for automotive and industrial applications. It offers adjustable voltage reference, regulated voltage outputs, variable current limiting, and integrated temperature sensing. It is suitable for a wide range of applications, where a stable voltage reference is required.
