PMIC - Supervisors: MAX6364PUT23-T Application Field and Working Principle
Power management IC (PMIC) supervisors are integrated circuits that monitor the power supply to detect power disturbance events and then take appropriate action when the desired voltage levels deviate too far from their specified range. This PMIC supervisor type provides integrated overvoltage, undervoltage, and overcurrent protection capabilities. This article will discuss the application field and working principle of MAX6364PUT23-T, which is a Small-Size, Low Power, SPI/Microwire-Compatible, Quadvoltage Supervisor with +1.8V Overvoltage Protection.
Application Field
The MAX6364PUT23-T makes an ideal single-chip power solution for processor and ASIC controllers, embedded controllers, or other applications that require monitoring of multiple supply rails. It is designed for embedded systems utilizing µPs or ASICs with one or more auxiliary supplies. It monitors four user-selected voltages and provides low-level logic outputs that occur when any of the user-programmed power cycles, overvoltages, or undervoltages are detected. This device also includes adaptive voltage protection, which allows sensitive components to be connected directly to its input power lines, preventing excursions above and below a set threshold.
The MAX6364PUT23-T comes with an adjustable 8-bit counter to provide an additional level of protection in the form of a watchdog timer. This timer can be used to reduce power consumption during the power-down sequence, or it can be used to detect and respond to any abnormal events in embedded applications. The device has open-drain outputs, allowing for a wide range of output voltage levels that can be used for alarm indicators and/or for system reset logic.
The MAX6364PUT23-T is designed to meet the stringent requirements of harsh automotive and industrial applications. It features a wide operating temperature range of -40°C to +125°C, allowing it to be used in extreme environments. Additionally, it features industry-leading on-resistance of 6 mΩ, enabling the lowest power dissipation in its class for long term operation. With its robust construction, small package size and low current-consumption, the MAX6364PUT23-T is the perfect choice for designs that require reliable power protection.
Working Principle
The MAX6364PUT23-T works by monitoring the four user-selected voltages (VIN1 through VIN4). It has a 5-bit digital-to-analogue converter (DAC) that is used to set the desired voltage thresholds for each voltage. When any of the voltages exceed their specified threshold, the output of the device is activated, triggering a reset or alert logic. The MAX6364PUT23-T also features an open-drain output, allowing for a wide range of output voltage levels that can be used for alarm indicators, system reset logic, and so on.
The integrated 8-bit counter can be used to provide additional protection from unexpected power loss. This counter can set the duration of the trigger of outputs, providing the user with the ability to choose the amount of time the outputs should be active after a power disturbance has been detected. This feature is especially useful in embedded applications, where it can prevent system crashes from occurring due to unexpected power loss.
The MAX6364PUT23-T is also equipped with adaptive voltage protection, which allows sensitive components to be connected directly to its input power lines and prevents them from being exposed to excursions above and below a set threshold. Additionally, it includes an integrated internal temperature sensor, which allows the user to adjust the threshold levels in order to ensure safe operation at higher temperatures.
In order to ensure optimal performance, the MAX6364PUT23-T includes an on-chip comparator and an adjustable hysteresis. The comparator is used to accurately monitor the voltage inputs and compares them to the user-defined thresholds. The adjustable hysteresis provides additional immunity from input voltage deviations due to noise or other external factors.
In summary, the MAX6364PUT23-T is an ideal power solution for applications that require reliable and robust monitoring of multiple supply rails. It is a small-size, low-power, SPI/Microwire compatible PMIC supervisor that provides an adjustable 8-bit counter, adaptive voltage protection, an integrated internal temperature sensor, and adjustable hysteresis. Furthermore, it is designed to meet the stringent requirements of harsh automotive and industrial applications, enabing reliable and robust power protection for the longest life possible.
