PMIC - Supervisors

Supervisor ICs are semiconductor integrated circuits designed to provide system monitoring of power consumption and voltage levels. The MAX6717UKSFD2+T is a microprocessor supervisor circuit designed to provide overvoltage and undervoltage protection for 3.3V or 5V microprocessors.

The MAX6717UKSFD2+T has two external components, a Resistor and a Capacitor, that allow the user to set parameters like voltage threshold, timeout delay, reset pulse width, and reset active state. The device also features an adjustable watchdog timer that can be used in conjunction with the reset output to provide system lockup protection.

Application Field

The MAX6717UKSFD2+T supervisor is suitable for use in systems that require protection from undervoltage and overvoltage conditions, such as desktops, servers, and other embedded systems. It can also be used to monitor and protect against power supply transients or brownouts, and is well suited for telecommunication applications.

Working Principle

The MAX6717UKSFD2+T supervisor works by monitoring the voltage supplied to the microprocessor or the voltage at an external voltage source or pin. When power levels drop to or exceed the specified threshold levels, the supervisor IC initiates a reset signal to reset the microprocessor or the entire system.

In addition to providing overvoltage and undervoltage protection, the MAX6717UKSFD2+T also features an adjustable watchdog timer that monitors system activity and resets the system if it fails to respond within the desired timeframe. The watchdog timer can also be used in conjunction with the reset signal to provide system lockup protection.

The MAX6717UKSFD2+T also features an active low open drain reset output that can be connected to an external active low reset device, such as a microprocessor, to reset the entire system. The active low reset signal is held low until the power supply rises above the shutdown threshold and a proper reset occurs.

Conclusion

The MAX6717UKSFD2+T is a microprocessor supervisor circuit designed to provide overvoltage and undervoltage protection for 3.3V or 5V microprocessors. The device has two external components, such as a Resistor and a Capacitor, that allow the user to set parameters such as voltage threshold, timeout delay, reset pulse width, and reset active state. In addition to providing overvoltage and undervoltage protection, the MAX6717UKSFD2+T also features an adjustable watchdog timer and an active low open drain reset output that can be connected to an external active low reset device, such as a microprocessor, to reset the entire system.
