REF3112AIDBZT

Power management integrated circuits (PMICs) are an important component in electrical power sources. The term ‘power management’ can be applied to any kind of electronic system which requires the supply of power to operate, from small consumer devices to industrial-level installations. Common examples of power management functions include voltage regulation, overcurrent protection and surge protection. Voltage references are an integral part of PMICs and are used to provide a stable and consistent output voltage, regardless of any environmental or system changes.

The REF3112AIDBZT is a precision voltage reference IC designed to offer an adjustable output range of 0.8V to 5.5V in automobiles and industrial systems. This low-power voltage reference is capable of providing voltage accuracy of ±3mV, and a low temperature coefficient of ±15ppm/°C. It is capable of operating over a wide range of input voltages, from 2.7V to 5.5V, with output voltage accuracy over temperature as low as ±1mV/°C.

The REF3112AIDBZT uses a band-gap reference topology to generate a constant voltage output. A band-gap reference is a circuit consisting of two precision diodes that have different currents and different temperature coefficients that can be combined to produce an output voltage independent of temperature. In the case of the REF3112AIDBZT, the circuit creates an output voltage of 1.2V, which is then adjusted with a potentiometer to achieve the desired output voltage of 0.8-5.5V.

The REF3112AIDBZT offers several features that make it an ideal choice for applications including automotive, industrial, medical and consumer electronics. It offers a low input bias current, low output voltage drift, high accuracy, and low power consumption. The low power consumption of the REF3112AIDBZT makes it attractive for automotive applications where power efficiency is essential. It also has a built-in under-voltage lockout circuit which helps prevent undesirable operation when the input voltage drops below a certain threshold.

In automotive applications, the adaptive voltage scaling feature of the REF3112AIDBZT provides the system with optimal power efficiency while maintaining a stable output voltage. The device is also able to withstand voltage spikes up to ±40V, which makes it suitable for use in high-voltage environments. Additionally, its low maximum operating temperature of +140°C allows for reliable operation in extreme temperature environments.

Overall, the REF3112AIDBZT is an excellent choice for automotive, industrial, medical and consumer electronic applications. With its low power consumption, wide input voltage range, high accuracy and temperature coefficient, it is an ideal choice for any project that requires a reliable and highly accurate voltage reference.
