The MAX6313UK30D4-T is a low-voltage supervisor integrated circuit (IC) designed to monitor up to six voltage levels. It is commonly used in power management, providing well-defined voltage thresholds and simple control logic, making it highly adaptable to a wide range of applications. As part of the MAX6313UK30D4-T IC family, the MAX6313UK30D4-T is a supervisor IC in the power management integrated circuit (PMIC) category.

The MAX6313UK30D4-T is a highly integrated IC with a wide operating temperature range and low power consumption. It comes with an integrated voltage monitor, a two-level reset system, an on-chip clock driver and an integrated window comparator. The MAX6313UK30D4-T has a low operating voltage range from +2.0V to +6.5V, making it well-suited for low-voltage and battery-powered applications.

Applications of the MAX6313UK30D4-T supervisor IC typically fall into one of two main categories: power management and reset sequencing. In power management applications, it can be used as a reset manager to ensure that all system peripherals start up correctly, or to monitor power supply voltages and ensure they are within safe operating range. In reset sequencing applications, it can monitor up to six input voltages, enabling the host processor to control the power-on of peripherals in a pre-defined sequence.

In terms of its working principle, the MAX6313UK30D4-T operates on a basic two-level reset system. When the voltage level of any of its monitored supply voltages falls below its lower threshold, it asserts its active-low RESET signal and clears its power-on reset (POR) output. The MAX6313UK30D4-T resets then remain asserted until the monitored voltages return to their normal levels. Once the voltage levels have returned to normal, the MAX6313UK30D4-T continues to monitor the voltages and will reassert its reset signals should any monitored voltage levels fall too low again.

The MAX6313UK30D4-T can also be configured to assert its reset and POR outputs signals on power-up using an integrated brown-out detector. This feature allows a system to reset itself automatically upon power-on or power-up, preventing the system from operating at potentially hazardous voltage levels. The MAX6313UK30D4-T also provides an external delay time adjustment option, allowing control of the minimum time after power-up that the POR is active before reset can be released.

In addition, the MAX6313UK30D4-T IC includes a window comparator circuit, which can detect when an input voltage remains static with certain pre-programmed limits. This allows the IC to detect voltage glitches, power failure events and power supply faults; and then issue a RESET signal accordingly. The integrated clock driver can also be used to further extend the brown-out detect feature, providing additional protection against power glitches and voltage sags.

Overall, the MAX6313UK30D4-T supervisor IC is an excellent choice for a wide range of applications where low voltage and battery powered applications are involved. It features a low operating voltage range, low power consumption, integrated voltage monitor and reset system, clock driver and window comparator circuit. Its integrated reset sequencing, brown-out detection, clock driving and window comparator features make it a very powerful and versatile solution for power management and reset sequencing applications.
