The MAX817MCSA+ is a versatile regulator from Maxim Integrated and available as a 14-Pin TSSOP or SOIC package. This chip supersedes the MAX817ASA and MAX817MCSA devices. The MAX817MCSA+ is an advanced power monitoring and management device that offers improved voltage supervision up to 10V. It can operate over a wide range of supply voltages (1.8V to 8.5V) with a typical consumption current of 5mA.
Introduction
The MAX817MCSA+ is designed to provide overvoltage, undervoltage and overcurrent protection in a wide range of applications. It can be used as a power supply supervisor, fail-safe reset circuit, system reset controller and overcurrent monitors. It also provides improved device reliability and accuracy compared to previous devices. The MAX817MCSA+ has configurable trip and reset points, an adjustable reset timeout, and an auxiliary power supply.
Applications
The MAX817MCSA+ is ideal for a variety of applications, including DC-DC power supplies, battery back-up applications, RAM and ROM controllers, ASICs, embedded systems, microprocessors and digital controllers. It can also be used as a voltage supervisor and reset manager for embedded systems that require improved monitoring accuracy. The device has been designed to provide reliable and accurate power supervision over a wide range of supply voltages in automotive, industrial and computing systems.
Features
The MAX817MCSA+ has several features that make it a superior regulator for power monitoring applications. It has an adjustable reset timeout of up to 2 seconds, a configurable reset threshold from 5V to 10V, and a configurable trip voltage between 1.8V and 10V. It also has a single auxiliary power supply and a wide operating temperature range of -40C to +125C. Additional features include an adjustable overcurrent threshold of up to 600A, an active low power and digital control inputs, and up to seven digital monitoring outputs.
Working Principle
The MAX817MCSA+ works using a voltage-controlled reset algorithm. The device takes the input voltage level, compares it to the internally set reset threshold, and then issues an active-low reset signal when deemed necessary. The device monitors and looks for a specific voltage level to be maintained. If the voltage falls below the reset threshold, the device issues a reset output signal. Once triggered, the reset output will remain active until the voltage exceeds the reset threshold level and the reset time-out period has elapsed.
The MAX817MCSA+ also contains a current limit feature that is configurable up to 600A. This feature prevents excessive current draw from damaging sensitive electronic components. If the current limit is exceeded, the device will issue a power-down reset command, reducing the output current and protecting the system from overload. This feature is highly beneficial for automotive and industrial applications, as it prevents system damage due to overcurrent conditions.
Conclusion
The MAX817MCSA+ is a versatile power management and monitoring device designed to offer improved voltage reliability over a wide range of supply voltages. It is a superior power supervisor, reset manager, and overcurrent monitor for embedded systems that require improved monitoring accuracy. The device has adjustable reset and trip thresholds, adjustable reset timeout and up to seven digital monitoring outputs. It also offers a wide operating temperature range of -40C to +125C, and a versatile current limit feature that allows it to protect the system from damage due to overcurrent conditions. The MAX817MCSA+ is the ideal solution for automotive, industrial, and computing applications.
