Maxim Integrated MAX933CSA Microprocessor Supervisory Circuits

The MAX933CSA from Maxim Integrated is a high-quality microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides a significant level of system reliability and accuracy required in critical applications, ensuring that your systems operate within their intended parameters.

This compact supervisory circuit comes in an 8-pin SOIC package, making it suitable for space-constrained applications. It is specifically engineered to maintain system integrity through monitoring and control of the power supply function. With its precise voltage monitoring capability, the MAX933CSA ensures that the µP and other devices are reset to a known state during power-up, power-down, and brownout conditions.

Key Features of the MAX933CSA:

  
• Power Supply Monitoring: Precise monitoring of the power supply voltage with a factory-trimmed reset threshold level.
  
• Low Power Consumption: The device features a low quiescent current, making it an ideal choice for battery-operated applications where power efficiency is critical.
  
• Reset Output: The MAX933CSA provides an active-low reset output, which remains asserted for a minimum reset timeout period after VCC has risen above the reset threshold.
  
• Manual Reset Input: A manual reset input is available, allowing for a system reset via an external pushbutton or logic signal.
  
• Wide Operating Voltage Range: The device operates over a broad voltage range, accommodating various system power requirements.
  
• Temperature Range: Designed to operate over the industrial temperature range, the MAX933CSA is suitable for harsh environments.

The MAX933CSA is a versatile component that can be used in a variety of applications including computers, controllers, intelligent instruments, and portable/battery-powered equipment. Its reliable performance and robust feature set ensure that it is an excellent choice for designers looking to enhance system stability and reduce the risk of data corruption due to power anomalies.

With Maxim Integrated's commitment to high-quality components, the MAX933CSA supervisory circuit is a dependable solution for maintaining the health and efficiency of your digital systems.
