Power management integrated circuits (PMICs) are devices used to control the flow of electricity and manage the power supply of a system. Supervisors are used to monitor system parameters, such as supply voltage levels, current draw, and temperature, in order to protect the system from exceeding safe limits. The MAX810SN120T1G is a supervisor PMIC from Maxim Integrated that is designed for portable applications requiring low power and long battery life.

Product Overview

The MAX810SN120T1G is a micro-power supervisor designed for use in portable systems, including cell phones, PDAs, and other battery powered applications. It has an operating voltage range of 2.2V to 5.5V, allowing it to be used in a variety of circuits and operating environments. The device offers a wide variety of features, including a low-voltage supervisor reset, watchdog timer reset, power-on reset, programmable reset time delay, and over-voltage reset.

In addition to these features, the MAX810SN120T1G includes a voltage detector circuit that can monitor system parameters and detect low voltage or over-voltage conditions. The device is able to provide a precision output signal at the programmed reset threshold, ensuring system protection. The supervisor is available in a small TSSOP-8 package, making it suitable for use in space-limited designs.

Application Fields

The MAX810SN120T1G is designed for a variety of portable applications, including portable electronic devices like cell phones, smart phones, PDAs, audio players, and other handheld devices. The micro-power supervisor provides protection against over-voltage, under-voltage, and over-temperature conditions, making it well-suited for use in battery powered applications. The device can also be used in automotive systems and industrial applications.

Working Principles

The MAX810SN120T1G is used to monitor the system voltage and provide reset signals to other system components when specific thresholds are crossed. The device includes a voltage detector circuit that is used to detect under-voltage or over-voltage conditions. When a condition is detected, the device will generate a reset signal at the programmed reset threshold. This reset signal can then be used to reset other system components, ensuring system protection.

In addition to providing reset signals, the MAX810SN120T1G can also be used to provide an interrupt signal, allowing the system to take action in the face of a detected fault. The device also includes a watchdog timer and power-on reset, enabling system-level power management and protection.

Conclusion

The MAX810SN120T1G is a supervisor PMIC from Maxim Integrated that is designed for portable applications requiring low power and long battery life. The device offers features such as low-voltage supervisor reset, watchdog timer reset, power-on reset, programmable reset time delay, and over-voltage reset. This micro-power supervisor is suitable for use in cell phones, PDAs, audio players, and other portable electronic devices. It can also be used in automotive systems and industrial applications for system-level monitoring, protection, and power management.
