Today, many applications such as automotive, industrial, communications, and medical require power management integrating functions like voltage supervisory, system reset, or watchdog timers. Among the various integrated circuit products is the MAX6313UK42D2-T, which is a part of the MAX6313 series of advanced, supervisory voltage and reset circuits sold by Maxim Integrated. It operates over a 1.5V to 6V input voltage range and can be used to ensure the reliability of an electronic system. It provides system reset and visibility of low, high, and power-on reset (POR) voltages.

Overview

The MAX6313UK42D2-T is a device with advanced power management functions, such as voltage supervisory, system reset and watchdog timer functions. It is a low supply current, 1.5V to 6V CMOS supervisory voltage reset IC. It can manage reset of the system in case of a power failure and can be used to detect the system freeze or the system reboot depending upon the configuration. It is offered in a 8-pin, ultra small uSOP packaging that optimizes board space. This device has a low operation current of 1 mA and provides low, high, and power-on reset voltages.

The MAX6313UK42D2-T supports watchdog timer with an adjustable timeout delay that ranges from 160 ms to 1.25 sec. It has an active low or EMI compliant active high reset output in order to ensure reliability. In addition, it includes adjustable reset threshold, enabling reset levels to be set as per application requirements. Furthermore, this device is offered in extended temperature range from -40°C to +85°C.

Application Fields

The wide input voltage range and comprehensive range of features of the MAX6313UK42D2-T make it suitable for several application fields. It is widely used in automotive, industrial, communications, and medical applications. It can be used to ensure the reliability of the system and reset thresholds can be adjusted as per application requirements.

The MAX6313UK42D2-T is also used in consumer electronics such as digital cameras, modems, audio/video devices, PDAs, and electronic toys. Its watch dog timer and reset functions make it ideal for use in these applications. Its extended temperature range allows it to operate reliably in the required temperature range ensuring a longer life span.

Working Principle

The working principle of the MAX6313UK42D2-T is based on the reset feature. It continuously monitors the supply voltage of the system. Once the voltage drops to a preset threshold, the reset output is activated and works until the supply voltage is restored to a normal level. This helps in resetting the system when the system freezes or reboots. The device also includes watchdog timer function that can detect system freezes and reset the system if it is not functioning properly. It offers adjustable reset threshold that helps in setting the reset levels as per application requirements.

The MAX6313UK42D2-T also offers EMI-compliant active high reset output. This feature helps in ensuring better system reliability and it is suitable for use in medical applications. It also offers a wide temperature range of -40°C to +85°C, allowing it to operate in a wide temperature range.

Conclusion

The MAX6313UK42D2-T is a low supply current, 1.5V to 6V CMOS supervisory voltage reset IC that offers a comprehensive range of features and functions. It is widely used in automotive, industrial, communications, and medical applications due to its wide input voltage range and reliable reset feature. It also offers adjustable reset thresholds, watchdog timer, and an EMI compliant active high reset output. It is also offered in an 8-pin ultra small uSOP package for optimized board space and offers extended temperature range from -40°C to +85°C. All in all, this device offers excellent reliability and performance.
