Maxim Integrated's MAX802LESA+ Supervisory Circuit

The MAX802LESA+ is a high-quality supervisory circuit designed and manufactured by Maxim Integrated, a company well-known for its reliable and innovative semiconductor products. This compact and efficient component is engineered to monitor power supplies in microprocessor systems, providing a crucial safety and management function that ensures stable and reliable operation.

At the heart of its features, the MAX802LESA+ offers a precision voltage monitor with a 4.65V threshold, which is ideal for 5V power supply systems. It is designed to assert a reset signal whenever the VCC supply voltage falls below its threshold, ensuring that the microprocessor and other critical components are reset properly. This reset signal is maintained for a minimum of 140ms after VCC rises above the reset threshold, providing ample time for the system to stabilize before normal operation resumes.

The device is available in an 8-pin SOIC package, making it suitable for space-constrained applications. Its low power consumption is a significant advantage for portable and battery-powered devices, ensuring that the power budget is utilized efficiently without compromising the supervisory functions.

Moreover, the MAX802LESA+ features a manual reset input, allowing for an external trigger to initiate a system reset. This is particularly useful for system maintenance, troubleshooting, or when a user-initiated reset is required. The manual reset function is both versatile and robust, accepting any reasonable logic level to activate the reset.

With its wide operating temperature range from 0°C to +70°C, the MAX802LESA+ is versatile enough to be used in a variety of environments, from standard consumer electronics to industrial applications. Its reliability is backed by Maxim Integrated's reputation for quality, ensuring that this supervisory circuit can be integrated into critical systems with confidence.

In summary, the MAX802LESA+ from Maxim Integrated is a compact, efficient, and reliable solution for power supply monitoring and system reset management. Its precision, low power consumption, and manual reset feature make it an excellent choice for a wide range of applications where consistent performance and uptime are essential.
