The MCP809M3-2.93 IC is a supervisor IC that provides high performance micro-processor system protection to multiple voltage rails. It is an ideal choice for high end applications, including datacenter, industrial, networking and telecom. It is a highly integrated supervisor IC with features such as programmable time delays, inhibit inputs and open drain output for reset implementation.

Overview

The MCP809M3-2.93 is a supervisor specifically designed for high end applications. It is based on a DeepCom™ technology and is offered in a SOT23-5 package. It incorporates a variety of features such as programmable time delays, a power status register and inhibit inputs for reset. The supervisor features low quiescent current and reset thresholds, making it an ideal choice for data centers, industrial systems, networking and telecom applications.

Application Fields

The MCP809M3-2.93 is an ideal choice for multiple voltage rail protection applications, including:

• Data Centers - Data centers require protection of their core systems to ensure reliable operations and eliminate downtime. The MCP809M3-2.93 provides several features that enable it to provide this critical protection, including programmable time delays and inhibit inputs.
• Industrial Systems - Industrial systems require a robust and reliable supervisor IC. The MCP809M3-2.93 meets those requirements, with a wide input voltage range and programmable time delays for a number of different voltage rails.
• Networking and Telecom - Networking and telecom systems are often placed in harsh and noisy environments, making it difficult for supervisors to accurately detect and respond to reset conditions. The MCP809M3-2.93 is designed to meet these challenging requirements, with its open drain output, low quiescent current, and wide input voltage range.

Working Principle

The MCP809M3-2.93 provides system protection to multiple voltage rails through a variety of features. At the heart of the MCP809M3-2.93 is a voltage supervisor IC. This IC is capable of monitoring up to five input voltage rails and providing a reset signal when any one of these rails is out of range. The supervisor IC also includes an inhibit input and an open drain output, allowing an external circuit to override the reset signal.

The MCP809M3-2.93 also includes three programmable time delays, allowing the supervisor to use a variety of reset-detection strategies. The TIMEOUT feature allows the supervisor to detect a change in the input voltage and then delay its response for a set amount of time. This can be used to eliminate false reset triggers that may occur due to noise or other transient conditions. The WATCHDOG timer is used to periodically check the input voltages, to ensure that the voltage rails remain within their preset range.

Finally, the MCP809M3-2.93 includes a power status register, which provides the host processor with real-time information about the status of each monitored voltage rail. This information can be used to take corrective action if a voltage rail falls out of range.

Conclusion

The MCP809M3-2.93 is a robust and highly integrated supervisor IC that provides system protection to multiple voltage rails. It includes a variety of features such as programmable time delays, inhibit inputs, and a power status register. These features make the MCP809M3-2.93 an ideal choice for data centers, industrial systems, networking and telecom applications.
