PMIC (Power Management IC) is a specialized integrated circuit used to manage the power of various electronic devices, including voltage references. Voltage references are electrical circuits that maintain a precise reference potential or voltage regardless of changes in the input or load. Voltage references are essential in semiconductor technology where devices turn an input current into an output voltage. The MAX6033C/AUT50#TG16 PMIC is a voltage reference IC specifically designed for harsh automotive environments. It ensures a high level of precision and accuracy while consuming very little power.

Features

The MAX6033C/AUT50#TG16 has a number of features:

• 10µA quiescent current allows for a wide temperature range.
• VREF output range from -390mV to +150mV with a temperature coefficient of ±2.5ppm/°C.
• High accuracy in both temperature and output.
• Improved automotive-grade electrostatic discharge protection.
• Six-bit digital-to-analog converter for enhanced programmability.

Application Field

The MAX6033C/AUT50#TG16 voltage reference is widely used in automotive applications due to its high performance. It can be used in various automotive control systems such as vehicle engine control units, transmission control units, and emission control units. In addition, the voltage reference can also be used in gas and metering sensors, safety monitoring circuits, fuel injectors, and other automotive components that require an accurate voltage reference.

Working Principle

The MAX6033C/AUT50#TG16 voltage reference maintains a precise reference potential regardless of changes in the input or load. It has an internal reference voltage of 1.25V (typical) and outputs a precise reference voltage from -390mV to +150mV, with a typical temperature coefficient of ±2.5ppm/°C. This is made possible by the voltage reference’s internal oscillator and error compensation circuit, which ensures desirable accuracy in the output voltage.

The voltage reference is designed for harsh automotive environments and is able to withstand extreme temperatures and sudden power interruptions. It has a built-in protective circuit which blocks current from flowing into the chip when the reverse supply voltage is over 10V and limits the max current in the VREF pin to 25mA. Additionally, the IC also features improved electrostatic discharge protection which prevents the IC from being damaged by transient voltage surge.

Conclusion

The MAX6033C/AUT50#TG16 PMIC is a common voltage reference IC used in automotive applications. It provides a reliable and accurate output voltage and is able to withstand harsh environmental conditions. It features improved electrostatic discharge protection, a low quiescent current, and a six-bit digital-to-analog converter for programmability. The MAX6033CS is a reliable and cost-effective solution for automotive control systems.
