It features an integrated voltage supervisor, high precision voltage reference, and temperature monitor with 0.25% accuracy over a -55°C to +125°C temperature range. The MAX6414UK30+T includes two low-voltage and two high-voltage comparators, two programmable watchdog and reset timers, a precision voltage reference, and a built-in temperature signal.

Applications

The MAX6414UK30+T can be used in a variety of applications, including precision microprocessor voltage monitoring, over- and under-voltage protection, system power sequencing, reset automation and control, watchdog timer supervision, and temperature monitoring.The MAX6414UK30+T is an ideal supervisor for battery powered products, as it has low power consumption and offers precise monitoring of the input voltage. It is designed to be used with microprocessors and digital signal processors where it provides voltage regulation, watchdog and reset timing, and temperature monitoring. It can also be used with embedded controllers, where it provides power supply and system reset control as well as over-voltage and under-voltage protection.

Working Principle

The MAX6414UK30+T is an integrated micro-supervisor device that is designed to monitor the power supply and operating environment of embedded systems and provide a safe operating range for microprocessors. It features two independent voltage comparators, two programmable watchdog and reset timers, a precision voltage reference, and a built-in temperature signal.The integrated voltage supervisor monitors the main supply voltages and supplies an active low reset signal when the input voltage falls below an adjustable reset voltage threshold. The second comparator can be used as an undervoltage detect (UVD) or as a second supervisor function. The MAX6414UK30+T also features a precision temperature-to-voltage converter that produces a 0.25% accurate output voltage over the full temperature of -55°C to +125°C.The watchdog and reset timers are used to generate a watchdog or reset signal if the processor does not respond within the specified timeout period. The timers can be programmed to generate a pulse or to reset the system when the timeout period is exceeded.The MAX6414UK30+T also offers a precision voltage reference that is accurate to 0.25%. The output voltage can be programmed to provide a regulated voltage source for the system, or it can be used as a reference for a trickle-charge circuit.

Conclusion

The MAX6414UK30+T is an integrated micro-supervisor device designed to monitor power supplies and operating environments, provide safe operating ranges for microprocessors and provide protection against over- and under-voltage protection, system power sequencing, reset automation and control, watchdog timer supervision, and temperature monitoring. Its integrated voltage supervisor, precision voltage reference, and temperature monitor provide precise monitoring and protection for embedded systems, making it an ideal choice for embedded applications.
