The MAX809REXR-T10 is a highly reliable and efficient supervisory circuit designed by Maxim Integrated, a company renowned for its innovative and high-quality integrated circuits. This microprocessor (µP) supervisory circuit is engineered to monitor power supplies in digital systems, ensuring that the system's microprocessor is reset to a known state during power-up, power-down, or brown-out conditions. The device is commonly used in a wide range of applications, including computers, controllers, intelligent instruments, and portable/battery-powered products.

Key Features

• Precision Monitoring: The MAX809REXR-T10 features a precision voltage monitor that keeps a close eye on the system's power supply, maintaining system integrity and reliability.
• Power-On Reset: It generates a reset signal whenever the supply voltage drops below a preset threshold, ensuring that the microprocessor starts operating in a known state.
• Manual Reset Capability: The device includes a manual reset input that allows for a reset to be triggered with an external push-button or logic signal, providing additional system control.
• Low Power Consumption: Designed for power-sensitive applications, it consumes minimal power, which is critical for extending the battery life of portable devices.
• Compact Packaging: The MAX809REXR-T10 comes in a compact, surface-mount SOT-23 package, which is ideal for space-constrained applications.
• Temperature Range: It operates over an extended temperature range, making it suitable for a variety of challenging environments.

Technical Specifications

The device has a threshold voltage typically set at 4.63V, with a ±1.5% threshold accuracy over the operating temperature range. It can handle a supply voltage range from 1.0V to 10V, and the reset output remains asserted for a minimum reset timeout period of 140ms after VCC has risen above the reset threshold level. The MAX809REXR-T10 is available in a 3-pin SOT-23 package, with the “T10” suffix indicating the specific configuration and packaging of the product.

Applications

The versatility of the MAX809REXR-T10 makes it suitable for a broad array of applications. It is particularly valuable in systems that cannot tolerate any uncertainty during power-up or power-down, including:

• Computers and Servers
• Embedded Systems
• Portable and Battery-Powered Devices
• Intelligent Instruments
• Industrial Controllers
