Maxim Integrated MAX708TCSA+T Microprocessor Supervisory Circuit

The MAX708TCSA+T from Maxim Integrated is a highly reliable and efficient microprocessor (μP) supervisory circuit designed to monitor power supplies and microprocessor activity in digital systems. It provides a crucial function by ensuring that the μP boots up in a known state and helps in preventing code execution errors during power-up, power-down, or brown-out conditions.

This supervisory circuit is particularly suitable for battery-powered equipment due to its low power consumption and compact size. The MAX708TCSA+T helps to enhance system reliability by providing functions such as reset output during power-up, power-down, and brown-out conditions, and a watchdog timer to ensure the μP is operating correctly.

Key features of the MAX708TCSA+T include:

• Power Supply Monitoring: Precision monitoring of 3.08V power supplies with a 200ms reset timeout delay ensures stable system operation and resets the μP whenever the supply voltage falls below the reset threshold.
• Watchdog Timer: A 1.6s watchdog timer (nominal) helps in recovering from software lock-up conditions by resetting the μP if it fails to strobe within the set time period.
• Manual Reset: An active-low manual reset input allows for an external trigger to initiate a system reset, providing additional control and security.
• Low Power Consumption: The device's low power consumption makes it an ideal choice for power-sensitive applications.
• Small Footprint: The MAX708TCSA+T comes in a compact 8-pin SO package, saving valuable board space in space-constrained applications.
• Temperature Range: It operates over an extended temperature range of -40°C to +85°C, making it suitable for industrial applications.

Whether you're designing computers, embedded systems, or portable consumer electronics, the MAX708TCSA+T provides the necessary protection and monitoring to ensure your system operates reliably under varying power conditions. With Maxim Integrated's commitment to high-quality components, the MAX708TCSA+T is a smart choice for designers looking to enhance system integrity and avoid costly downtime.
