The MAX6865UK24D4S+T is a precision power-supply supervisor designed to monitor the status of four power supplies and two temperature sensors. The MAX6865UK24D4S+T belongs to the PMIC (power management integrated circuit) class of components known as Supervisors. These components are used to detect faults in power-supply voltage and temperature levels, and are extremely important in assuring the stability and continuity of devices operating from in-circuit power.
The MAX6865UK24D4S+T\'s application field is broad and varied, ranging from automotive, industrial, to consumer and infrastructure markets. Typical applications include routers, modems, set-top boxes, bluetooth and other wireless communicators, home audio systems and automotive infotainment, government and military systems, medical monitors and equipment, and many more. Generally speaking, wherever there is a need to ensure continuous and safe operation of a device, this superb supervisor can be used to ensure that voltage and temperature levels remain within acceptable boundaries.
The MAX6865UK24D4S+T is designed to monitor four independent power supplies, providing both low and high voltage, over/undervoltage and short-circuit protection. In particular, it allows comparison of four voltage inputs against two programmable reference voltages, permitted deviations, and delay times. This dynamic monitoring helps prevent system failure due to illicit operation conditions.
Furthermore, the supervisor includes additional safety mechanisms such as a push-button switch, which is able to monitor the user configuration and out-of-range conditions. This feature provides a certain degree of protection against user device interference. It is also used to activate/deactivate certain functions/devices.
The MAX6865UK24D4S+T also allows for sensing of two temperature sources. Each temperature source has its own resistance-to-digital converter and trip points, allowing comparison of the two against two programmable temperatures and trip conditions. In addition, a polarity detection mechanism is included, which indicates whether the temperature source is connected to ground or to a voltage larger than 2 volts. This mechanism enables the supervisor to detect temperature sources which are not correctly connected, thus increasing device safety.
In terms of working principle, the MAX6865UK24D4S+T employs an analog programmable voltage detector and a digital circuitry to ensure safe operation of in-circuit powered devices. The voltage detector performs low and high voltage and short-circuit detection, and its output is compared to internal voltage reference thresholds. The digital circuitry then compares the voltage detector output to two programmable thresholds, and can activate/deactivate devices depending on the comparison results.
The MAX6865UK24D4S+T also includes two temperature sensors with their own digital circuitry, which performs temperature measurement and comparison with the programmable thresholds, and can modify device operation depending on the comparison results. This helps the supervisor to ensure a continuous, safe and energy efficient operation of the device.
The MAX6865UK24D4S+T is a compact, highly advanced supervisor which is used for reliable, safe and continuous operation for a wide variety of applications. It is designed to perform low/high voltage and temperature detection and comparison, and can activate/deactivate devices depending on the results of these comparisons. In addition, the supervisor includes several safety mechanisms such as a push-button switch, thus ensuring that only authorised personnel can access the device.
