Introduction
MAX8214ACSE+ is a Protect and Supervisor IC (PMIC) that offers solutions for many Supervisory and Protection purposes. This product combines several protection functions together, including reset detection, voltage monitoring, and current monitoring, making it an ideal solution for a variety of application field.
Application Field
MAX8214ACSE+ is well suited for use in distributed power systems. It is able to monitor current and voltage levels in both positive and negative supply rails, and it can detect out of specification parameters for both of these values. This PMIC is able to detect over-voltage, under-voltage, and over-current conditions and act accordingly by asserting its outputs. Additionally, due to its user-adjustable reset threshold and reset timeout, it can also serve as a watchdog timer.
MAX8214ACSE+ is also well suited for systems where both over-temperature and over-voltage conditions need to be monitored. It features an auto-retry function to compensate for any accidental or erroneous detection errors, as well as a power-on reset generator that ensures that any system reset is done safely and reliably.
MAX8214ACSE+ can also be used in portable and automotive applications. Its small size and low quiescent current make it suitable for applications where power consumption is critical. Its auto-retry capability coupled with its user- adjustable reset thresholds make it an ideal solution for automotive systems. It can be used in applications where both over-voltage and over-temperature protection are required.
Working Principle
The working principle of the MAX8214ACSE+ involves monitoring both voltage and current. It will detect any out of specification values and assert its outputs accordingly. It has two outputs: one for reset and one for interrupt. The reset output is asserted when an over-voltage or undervoltage condition occurs. The interrupt output is asserted when an over-current condition is detected.
The MAX8214ACSE+ also features a user-adjustable reset threshold and reset timeout. When the reset threshold is exceeded, the reset output is immediately asserted. The reset timeout feature allows the reset to be held active for a certain time after the signal has been acknowledged by the user and any current activity is stopped. This ensures that the reset condition is reliable and can be effectively used as a watchdog timer.
The MAX8214ACSE+ also has an auto-retry function that compensates for any accidental or erroneous detection errors. This ensures that any system reset is done safely by monitoring for any potential errors and retrying the operation. This feature allows for reliability and robustness in a variety of application fields.
Conclusion
In conclusion, MAX8214ACSE+ is a versatile PMIC – Supervisor IC. It offers a variety of protection and Supervisory functions, including current and voltage monitoring, auto-retry, and user-adjustable reset thresholds. This makes it a great solution for distributed power systems, portable and automotive applications, and other applications where over-voltage and over-temperature protection are required. It is also a great solution for watchdog timers due to its reset timeout and user adjustable reset threshold.
