Product Overview: MAX690SESA+ from Maxim Integrated

The MAX690SESA+ is a highly reliable, precision microprocessor (µP) supervisory circuit designed and manufactured by Maxim Integrated, a renowned leader in the development of innovative analog and mixed-signal products. This compact device is engineered to monitor power supplies in µP and digital systems, providing a significant safeguard against system failures due to unstable or failing power sources. It ensures that the µP is reset to a known state during power-up, power-down, and brown-out conditions.

Key Features

• Voltage Monitoring: The MAX690SESA+ provides accurate monitoring of the power supply voltage, ensuring that the system operates within the safe voltage threshold. It features a preset reset threshold voltage, which triggers a reset signal to the µP when the supply voltage drops below the acceptable range.
• Reset Output: The device offers an active-low reset output, which remains asserted for a minimum of 200ms after VCC has risen above the reset voltage threshold. This ensures that the µP and other critical components have sufficient time to stabilize before the system resumes operation.
• Low Power Consumption: Designed for energy-efficient operation, the MAX690SESA+ consumes minimal power, which is crucial for battery-powered devices and applications where power conservation is a priority.
• Wide Operating Temperature Range: The device operates effectively across a broad temperature range, making it suitable for use in various environments and applications.
• SOIC Package: The MAX690SESA+ comes in an 8-pin SOIC package, which is ideal for space-constrained applications. Its small footprint allows for integration into compact system designs without compromising performance.

Applications

The MAX690SESA+ is versatile and can be used in a wide array of applications, including:

• Computers and servers
• Embedded systems
• Portable/battery-powered equipment
• Data storage systems
• Industrial controls

With its robust feature set and Maxim Integrated's commitment to quality, the MAX690SESA+ is an excellent choice for designers looking to enhance system reliability and performance through superior power monitoring and reset capabilities.
