The MAX811TEUS-T is an application supervisor from Maxim Integrated Products. It is designed to control system power-up sequences, provide power supply sequencing and power supply regulation, monitor system voltages and currents, and protect the system from an over-temperature condition.The device is comprised of a power supply supervisor and a system supervisor in a single package. The power supply supervisor provides sequential start-up of system power supplies by using a step-down regulator. It monitors system-level voltages and automatically controls power supply sequencing based on pre-defined thresholds.The system supervisor monitors system-level voltages and currents, and both open drain and active-high reset outputs to detect a fault. It also has an integrated temperature sensor to provide protection against an over-temperature condition.The device supports an operating temperature range of -40°C to +85°C and is available in 8-pin VDFPN and QFN packages. It is suitable for a wide range of applications including industrial, automotive, and consumer electronics. Principle of Operation
The MAX811TEUS-T operates by monitoring system-level voltages, currents, and temperatures, and driving reset and power enable outputs when it detects a fault. The device has two main operation modes: normal mode and manually reset mode. In normal mode, the device monitors system supply voltages and currents, compares them to user-defined thresholds, and drives reset and power enable outputs as needed. In manually reset mode, the reset output is driven low when it detects a fault, and then is reset by a manual reset on the device\'s reset input pin.The device also monitors an external temperature and drives the reset output low when the external temperature exceeds a user-defined temperature limit. This prevents the system from operating at an excessive temperature, and allows the device to respond quickly to thermal conditions.The device operates over a wide range of voltages, currents, and temperatures with over-temperature prevention, providing a high level of system protection.Applications
The MAX811TEUS-T is an ideal choice for a wide range of applications, including industrial automation, automotive, and consumer electronics.The device can be used as a supervisory circuit for power supplies and power sequencing, as a reset controller for monitoring system-level voltages and currents, and as an over-temperature protection circuit.The device is programmed through the digital interface, allowing for a flexible system design. It features an adjustable reset time and reset threshold, providing a high degree of accuracy.The device is housed in a small package, making it suitable for applications with limited space.In conclusion, the Maxim Integrated Products MAX811TEUS-T is a versatile and reliable device, suitable for a wide range of applications requiring advanced system protection. It is small enough to fit into space-constrained applications and has extensive programming options, providing a high degree of flexibility and accuracy.
