PMIC supervisors, or voltage monitors, are integrated circuits that provide supply voltage monitoring, brownout and power-on reset functions for microprocessors and digital systems. The MAX6307UK49D2-T is a low-cost, single-channel supervisors that supplants traditional discrete voltage monitoring schemes. This application note will discuss the application fields and working principles of the MAX6307UK49D2-T.
Features
The MAX6307UK49D2-T features a low-cost, micropower voltage monitor with an adjustable reset output. It offers a wide operating voltage range from 1.0V to 5.5V, making it a suitable choice for applications that require a low-voltage reset in portable electronics, embedded systems, and 3V microprocessors. It features a manual reset input for system diagnostics, and an active-low push-pull reset output that has an open-drain/CMOS compatible polarity select. It also includes a wide hysteresis of 150mV, giving microprocessor systems effective brownout protection.Applications
The MAX6307UK49D2-T is suitable for low-voltage microprocessor systems, digital power supplies, and power-on reset applications in embedded systems. Its low-cost and wide operating voltage range make it an ideal solution for computers, PDA’s, telephones, and other portable electronics.Working Principles
The MAX6307UK49D2-T features a voltage monitor for providing reset to microprocessor and digital systems. The device senses the power supply voltage through an internal voltage divider that is adjusted with an external resistor. When the power supply voltage drops below the preset threshold voltage, the reset output is activated, preventing system failure or improper operation due to under-voltage conditions.The internal voltage divider allows the device to provide accurate reset detection and a wide input voltage range. The reset threshold voltage can be adjusted by choosing the value of the external resistor connected to the divider. A wide hysteresis of 150mV ensures that the output is not activated and deactivated too quickly, providing the system with effective brownout protection.The reset output is active-low push-pull, with an open-drain/CMOS compatible polarity select. This allows the device to be used in systems that require an active-low or active-high reset signal. The output also features a manual reset input for system diagnostics.Conclusion
The MAX6307UK49D2-T is a low-cost, single-channel voltage supervisor suitable for a wide range of low-voltage microprocessor systems. It features a wide operating voltage range and manual reset input, allowing it to provide reliable reset activation and deactivation. With its adjustable reset output and wide hysteresis, the MAX6307UK49D2-T is an ideal choice for systems requiring effective brownout protection.The specific data is subject to PDF, and the above content is for reference
