PMIC (power management integrated circuits) are important instruments for powering electronic systems. A PMIC can control the voltage, current, and temperature of a system and provide protection and advanced power management features. The MAX6310UK36D1-T is an example of a PMIC, specifically a supervisor.

Supervisors are a type of PMICs used to monitor system parameters. They detect excessive voltage, current, and temperature, and activate system reset or interrupt signals when required. The MAX6310UK36D1-T is a low-cost, low-power supervisor with an operating temperature range of -40°C to +85°C.

Application Field

The MAX6310UK36D1-T is used in battery-powered and other low-voltage applications. It has a minimum supply voltage of 1.5V and a maximum of 5.5V, with an input threshold range of 1.5V to 5.25V. It provides integrated protection from overvoltage, undershoot, and overcurrent conditions.

The MAX6310UK36D1-T has 2 channels for different voltages, for controlling two separate voltage inputs. This is useful for devices that require two separate voltage input levels, such as those with a battery backup system.

The MAX6310UK36D1-T also employs undervoltage lockout (UVLO) to prevent the system from turning on improperly, or at a voltage that would cause damage. It comes with a 1.8 ms reset pulse width and adjustable reset active time, making it useful for a variety of applications.

Working Principle

The MAX6310UK36D1-T has an advanced power management feature called Power-On Reset (POR). When power is applied to the PMIC, the POR circuit immediately activates, which sends a reset or an interrupt signal to the processor. Such a signal indicates that the processor is ready to be powered on and run its power-up sequence.

The MAX6310UK36D1-T also features a “watchdog” circuit. The watchdog is triggered if it does not receive regular reset signals from the processor. If the processor isn’t responding or functioning as expected, the watchdog will generate a reset signal, thus allowing the processor to reset itself and start its power-up sequence.

The MAX6310UK36D1-T also includes over voltage, over current, and thermal protection. If a voltage or current spike is detected, the PMIC will automatically switch off the system. Similarly, if the temperature of the system exceeds its threshold, the PMIC will shut off the system to protect it from damage.

The MAX6310UK36D1-T is also used in advanced applications, such as auto-restarting a system after a system crash or halt. This is done by setting up a timer, or by monitoring the processor’s internal temperature. If the processor’s temperature rises above a certain threshold, the MAX6310UK36D1-T will automatically shut off the system and then restart it again.

In conclusion, the MAX6310UK36D1-T is an ideal choice for a variety of applications, due to its two-channel capability, low-power operation, and integrated protection features. Its Power-On Reset, watchdog, and thermal protection features are a welcome addition. Its wide operating temperature range and low cost make it a suitable choice for both battery-powered and other low-voltage applications.
