Introducing the MAX809TW Microprocessor Reset Circuit from NXP Semiconductors

The MAX809TW, crafted by the renowned NXP Semiconductors, is a compact, three-pin, microprocessor (µP) supervisory circuit that provides a reliable solution for monitoring power supplies in µP and digital systems. It provides a significant function by asserting a reset signal whenever the VCC supply voltage drops below a preset threshold, ensuring the proper startup and operation of the µP during power-up, power-down, or brown-out conditions.

Key Features of the MAX809TW:

• Precision Monitoring: This device is designed to maintain system integrity by precisely monitoring the power supply voltage. It holds the µP in a reset state until the supply voltage reaches a stable and acceptable level, safeguarding the system from unpredictable behavior.
• Manual Reset Input: The inclusion of a manual reset input provides additional system control, allowing for a reset to be triggered externally as needed for system maintenance or troubleshooting.
• Low Power Consumption: With its low power consumption, the MAX809TW is an ideal choice for power-sensitive applications, ensuring that the additional supervisory function does not significantly impact the overall energy efficiency of the system.
• Wide Operating Voltage Range: The device operates over a wide voltage range, accommodating various application requirements and ensuring compatibility with a broad range of µP and digital systems.
• Temperature Stability: The reset threshold is stable over the entire temperature range, providing reliable performance regardless of environmental conditions.

Applications:

The MAX809TW is versatile and can be employed in a diverse array of applications. It is particularly well-suited for portable devices, computers, embedded systems, and other digital applications that require a stable and reliable reset function.
