MAX6388XS42D2-T

The MAX6388XS42D2-T is a supervisory device from Maxim’s Power Management Integrated Circuit (PMIC) portfolio. It belongs to the class of programmable microprocessors and supervisor ICs, designed to restart systems in the event of system reset or brownout. This single channel part is designed specifically to provide over-voltage/-current protection to +12V supplies, with inbuilt over/under-voltage and thermal shutdown capability. It is programmable over its wide input voltage range and offers user-selectable hysteric and reset timeout settings, as well as configurable trip and reset voltage level settings. It also integrates a logic circuit to the IC, enabling it to communicate alert signals to the system main processor, indicating which events have occurred.

The MAX6388XS42D2-T has a wide application range, as it is capable of protecting sensitive electronic circuits, or isolating hazardous voltages that could cause damage. Its functioning features, as well as its overvoltage and undervoltage protection capability, make it suitable for a range of applications. Firstly, it can be used for automotive applications, where it can be used to protect ECUs from the damages of shock and vibration due to its built-in logic and comparator circuit, as well as its fixed protective thresholds. Secondly, it can be used in industrial settings, particularly in high-end industrial settings that require high-voltage protection. Finally, it is suitable for consumer applications that require a low-cost, easy installation, and reliable over-/under-voltage protection.

The MAX6388XS42D2-T works on a system of over-voltage/under-voltage comparison and on-chip logic. This means, the input voltage to the IC is compared to an internal reference voltage that has been set by the user. In the event that the input voltage exceeds, or goes below the preset reference voltage, an internal comparator unit presents a logic high value to the on-chip logic circuit. The on-chip logic then activates the trip output or reset output as configured by the user, and also sends an alert signal to the system’s processor chip indicating the nature of the event. This logic circuit enables the MAX6388XS42D2-T to be able to latch up, or reset itself after a predetermined duration, and perform a fault-tolerant function.

The MAX6388XS42D2-T is also equipped with other features that help it in its operation. Firstly, it integrates a temperature sensor - which upon sensing an extremely high temperature, triggers a self-drive output, thereby turning off the system. Secondly, it also integrates a high-voltage clamp that helps it to limit the reversed current flow in the case of an over-voltage event and thereby, preventing damage to the IC. Finally, it is also equipped with debounced logic inputs and enables user-selectable reset timeout settings, ensuring that the system is restarted once the voltage level coincides with the set reference voltage.

Overall, the MAX6388XS42D2-T is an essential component of power management design suitable for multiple system designs. Its wide application range and programmable features- makes it an ideal choice for automotive, industrial and consumer applications requiring over-voltage/under-voltage protection. Furthermore, its onboard temperature-sensing and reverse-current-protection features help support its functions, thereby making it a power manager that is reliable and cost-effective.
