Supervisors are an integral part of the power management system, as they play a vital role in ensuring that the system works as intended. The MAX16081UR30Q+T is an Integrated Low-Voltage Supervisory IC that has been designed to provide a comprehensive suite of hardware and software features to help create a monitored, safe, and reliable power system. This device’s applications, features, and working principle are discussed in the following sections.

Applications of the MAX16081UR30Q+T

The MAX16081UR30Q+T supervisor IC is primarily used in automotive applications such as in car infotainment systems, navigation systems, and audio systems. Additionally, this device can be used in medical, industrial, communications, and other market applications. Some of the key features of this device and its usefulness in these designs include:

• Programmable undervoltage lockout (UVLO) and overvoltage protection (OVP) thresholds.
• Wide input voltage range (2.5 to 5) V.
• High efficiency buck or boost regulator.
• Integrated power-on reset (POR) and auto-reset (AR) function.
• Integrated watchdog and one-time-programmable (OTP) memory.
• Serial peripheral interface (SPI) support.
• Advanced system supervision and fault handling capability.
• Secure locking of the system configuration.

These features combine to make the MAX16081UR30Q+T a suitable, feature-rich device for applications that require reliable monitoring and robust power system protection.

Working Principle

The MAX16081UR30Q+T supervisor IC is designed to monitor the system power and guard against power-related faults. The device monitors the input voltage to ensure that it stays within the high and low voltage limits, and can detect both undervoltage and overvoltage faults. In the event of an undervoltage fault, the device will signal an interrupt to the microcontroller and either shut down the power supply or provide an alternate power source.

The device also has an integrated watchdog timer that can detect any system malfunctions or unstable conditions. If a fault is detected, the device will reset the system and put it into a safe state. The MAX16081UR30Q+T also includes OTP memory, allowing secure locking of the system configuration. This ensures that the system is protected even if it is subject to a malicious code attack.

Furthermore, the device can detect current faults, enabling it to shut down the system before the power supply can cause any damage. This is particularly useful in applications such as automotive, where it is necessary to react quickly to prevent damage in the event of a fault.

Conclusion

The MAX16081UR30Q+T is an integrated low-voltage supervisor IC that provides a comprehensive suite of features to help create a monitored and reliable power system. This device is suitable for automotive, medical, industrial, communications, and other market applications. The device is designed to monitor the system power and guard against power-related faults, making it an essential part of any power management system.
