The MAX6334UR23D3+T supervisors from Maxim Integrated provide reliable and accuracy supply monitoring for customer applications. This supervisor is designed to support microprocessor (uP) and logic circuits with low power consumption, along with its low quiescent current for a wide range of power sources including batterypacks, distributed power buses and AC/DC adapters. Its small footprint and integrated voltage supervisor, with high accuracy (1.25%) and wide temperature range (-40°C to +125°C), make it a supreme solution for reliable system power. This article will explore the application field and working principle of the MAX6334UR23D3+T supervisors.

Application Fields

This supervisor is primarily used in customer applications that require reliable and accurate supply monitoring and performance in extreme temperature environments. It can withstand up to 48V input voltage, making it ideal for distributed power applications, as well as applications such as automotive, industrial, and medical that require a wide temperature range (-40°C to +125°C).

The supervisor is widely used in systems where reliable power monitoring is a critical requirement. It was designed for systems that require a low quiescent current and small footprint, such as hand-held or mobile battery operated devices and distributed power buses. It is also used in automotive applications that require very high temperatures. Furthermore, it is suitable for applications such as industrial, medical, and consumer that must achieve high accuracy and reliability at an economical price.

Working Principle

The MAX6334UR23D3+T supervisors offer a comprehensive solution for monitoring the supply voltage of customer applications. It includes an input voltage supervisor with 1.25% accuracy and wide temperature range (from -40°C to +125°C). Furthermore, it includes a low quiescent current to reduce power consumption. The supervisor offers an output voltage threshold window with an ERROR output that signals when the input voltage is out of bounds. Additionally, it includes an enable input that can be used to enable/disable the supervisor.

The supervisor monitors the voltage of the power supply, and it features an output voltage threshold window that consists of a nominal input voltage and reference voltage. When the monitored voltage is within the prescribed window, the output will be high and normal operations can resume. When the monitored voltage is outside of the acceptable window, the ERROR output will be low, signaling that the voltage is either too low or too high and needing to be addressed.

The MAX6334UR23D3+T supervisors also provide additional features such as a power-on reset (POR) timer, which delays the start-up of the system until the power supply is stabilized, and a wide operating temperature range which allows it to operate in harsh environments. Moreover, it includes a low quiescent current, to reduce power consumption, and it has a small footprint, resulting in a cost effective solution.

Conclusion

In summary, the MAX6334UR23D3+T supervisors from Maxim Integrated provide reliable and accuracy supply monitoring for customer applications. It is capable of withstanding up to 48V input voltage, making it ideal for distributed power applications and for applications such as automotive, industrial, and medical that require a wide temperature range (-40°C to +125°C). This supervisor includes an output voltage threshold window with an ERROR output which signals when the input voltage is out of bounds, and it also includes a POR timer and a low quiescent current to reduce power consumption. It is the ideal solution for reliable system power.
