Power management integrated circuits (PMICs) are used to manage power in a system in an efficient and cost-effective manner. Supervisors are PMICs that provide voltage monitoring and reset capabilities for microcontrollers, microprocessors and other integrated circuits. The MAX6865UK32D4S-T is a 32-pin supervisor from Maxim Integrated, designed to provide voltage and temperature monitoring and reset capability for microprocessors and other integrated circuits.

Application Field of MAX6865UK32D4S+T

The MAX6865UK32D4S-T provides a total of seven independent supervisors in a single package. The MAX6865UK32D4S-T operates from a single 2.5 V to 6.5 V supply, with a supply current of 1.2mA typ and 3 mA max. It offers factory-trimmed thresholds and a wide range of activation delays to adapt as needed. It features an adjustable resettable delay from 10 μs to 5 s and a programmable, window-based thermal protection shutdown.

The MAX6865UK32D4S-T can be used in a variety of applications such as computers and handheld communication devices, portable media communications, and set-top boxes. It is suitable for monitoring and resetting various microprocessors, FPGAs, ASICs, and other integrated circuit devices. In addition, it can be used in automotive, industrial, and home applications.

Working Principle of MAX6865UK32D4S+T

The MAX6865UK32D4S-T’s main function is to monitor the power supply for a microcontroller to ensure that the supply voltage is within proper limits. The MAX6865UK32D4S-T also provides over-temperature and under-temperature protection with programmable reset delays, and it can be used to reset a microcontroller in the event of an over-voltage or under-voltage condition. The MAX6865UK32D4S-T also provides open-drain reset outputs, which can be used to reset additional devices in the system.

The MAX6865UK32D4S-T features an adjustable reset delay, which can be set as required to ensure that the device is not accidentally reset when the supply voltage goes below the set threshold. When the voltage falls below the threshold, the MAX6865UK32D4S-T toggles the reset output, indicating that the device should be reset or powered down to ensure proper operation. The device also features adjustable over-temperature protection, which can be used to protect the system from heat-related issues.

The MAX6865UK32D4S-T also features a few additional features, such as an open-drain output that can be used to indicate if the device has detected an over-temperature or over-voltage condition. Additionally, it has a selectable reset interrupt pin that can be used to detect if the device has been reset, and a watchdog timer that can be used to force a reset if the device stops responding.

The MAX6865UK32D4S-T is a versatile PMIC supervisor that is designed to provide voltage, temperature, and reset monitoring and protection for microcontroller and other integrated circuits. With its adjustable thresholds, adjustable reset delay, and programmable thermal protection, the MAX6865UK32D4S-T is capable of providing effective power management and protection for many different applications.
