Power management ICs (PMICs) are essential components of modern electronic systems. They regulate the supply of power to various components such as processors and memory in the system, allowing them to function optimally and reliably. PMICs are of many different types, the most common of which are voltage regulators, switch regulators, linear regulators, and supervisors.

Supervisors are microcontrollers that monitor the performance of other components in the system and provide alert signals when any of them begin to malfunction. The MAX6319MHUK27C+ is an example of a supervisor PMIC. This device is designed for use in automotive, industrial, telecom, and consumer applications.

Application Field

The MAX6319MHUK27C+ is a low-power, high-performance supervisor device that is well suited for automotive, industrial, telecom, and consumer applications. This supervisor offers a flexible combination of power supply supervisor functions, including voltage, current, temperature, and rate monitoring; performance control; and overcurrent protection. This PMIC is also very reliable, enabling it to maintain functionality over a wide temperature range and withstanding high levels of transient voltage. This makes the device specially suitable for use in extreme environments. The MAX6319MHUK27C+ is also compliant with semiconductor industry ESD standards and is certified for automotive applications.

Working Principle

The MAX6319MHUK27C+ is a three-in-one supervisors PMIC, providing built-in overvoltage protection, overcurrent protection, and overtemperature protection. This PMIC monitors either one or two power rail voltages with independent voltage monitoring for each rail. The voltage threshold values can be set using the device\'s internal configuration registers. The device also has an internal temperature sensor which monitors the ambient temperature, allowing the system to react accordingly in the event of excessive temperatures.

In addition to monitoring conditions, the MAX6319MHUK27C+ also provides reset and alert outputs which can be used to trigger system-level responses. The reset outputs can be set to active low, active high, MOSFET, and open drain logic levels. The alert output is an active high open drain logic level and can be configured to trigger at either the voltage or temperature thresholds. The device also features adjustable programmable time-out periods and has an adjustable reset delay time ranging from 1.5µs to 8.2ms. This allows for finely tuned response systems depending on the application of the device.

The MAX6319MHUK27C+ is a high-performance supervisor PMIC suited for use in automotive, industrial, telecom, and consumer applications. This device offers integrated overvoltage, overcurrent and overtemperature protection and can be programmed to provide reset and alert outputs in different logic levels. With its wide temperature range and reliable performance, the MAX6319MHUK27C+ is an ideal choice for powering mission-critical systems in extreme conditions.
