Maxim Integrated MAX706SESA+T Microprocessor Supervisory Circuit

The Maxim Integrated MAX706SESA+T is a compact, highly-reliable supervisory circuit designed to monitor power supplies and microprocessor activity in digital systems. It provides essential functions to safeguard system integrity by monitoring the power supply voltage and ensuring that the microprocessor is reset to a known state during power-up, power-down, or brown-out conditions. This device is an ideal solution for managing system resets in microcontrollers, computers, controllers, and intelligent instruments.

This supervisory circuit offers several key features that make it a valuable addition to any sensitive digital system. It has a precision voltage monitor with a 4.65V threshold, ensuring accurate detection of under-voltage conditions. The reset output is guaranteed to remain in the active state for a minimum of 200ms after VCC has risen above the reset voltage threshold, providing ample time for the system to stabilize.

The MAX706SESA+T comes in a compact 8-pin SOIC package, which makes it suitable for space-constrained applications. It operates over a wide supply voltage range of 1.0V to 5.5V, which allows it to be used in a variety of systems with different power requirements. Additionally, the low supply current of only 12µA (typical) is advantageous for power-sensitive applications.

Another important feature of the MAX706SESA+T is its manual reset capability. This allows for a system reset to be triggered manually, providing an additional layer of control for system operators. The device also includes a watchdog timer that forces the microprocessor into a reset state if it fails to strobe within a preset time frame, enhancing the system's safety and reliability.

Maxim Integrated's commitment to quality is evident in the MAX706SESA+T, which is designed for operation over the extended industrial temperature range of -40°C to +85°C. This makes it robust enough to operate in harsh environments, ensuring system stability and reliability.

In summary, the MAX706SESA+T is a versatile, reliable, and efficient solution for microprocessor supervisory needs. Its combination of precision monitoring, low power consumption, and compact form factor makes it an excellent choice for a wide range of applications where system integrity is paramount.
