DS1815-5+

DS1815-5+ Description

The DS1815-5+ is a single-channel voltage supervisor IC from the EconoReset series, manufactured by Analog Devices Inc./Maxim Integrated. This device is designed to monitor a single voltage supply and provide a reset signal when the monitored voltage falls below a specified threshold. The DS1815-5+ features a voltage threshold of 3.06V and a minimum reset timeout of 100ms. It is housed in a Through Hole package, specifically the TO92-3 format, and is available in bulk packaging.

DS1815-5+ Features

• Voltage Monitoring: The DS1815-5+ is designed to monitor a single voltage supply, ensuring that the system remains stable and reliable. The voltage threshold is set at 3.06V, providing a precise monitoring point for critical power supplies.
• Reset Functionality: The reset signal is active low, meaning it asserts a low signal when the monitored voltage drops below the threshold. This feature is crucial for resetting microcontrollers or other system components when a power supply issue is detected.
• Reset Timeout: The device has a minimum reset timeout of 100ms, ensuring that the system has sufficient time to stabilize before the reset signal is released. This helps prevent premature resets and ensures reliable system operation.
• Through Hole Mounting: The DS1815-5+ is designed for through-hole mounting, making it suitable for applications where surface-mount components are not feasible. This type of mounting is often preferred for prototyping and applications requiring robust mechanical stability.
• Compliance and Status: The DS1815-5+ is REACH unaffected and ROHS3 compliant, ensuring it meets environmental and safety standards. The product is currently marked as obsolete, but it remains a viable option for legacy systems and specific applications where its features are required.

DS1815-5+ Applications

The DS1815-5+ is ideal for a variety of applications where reliable voltage monitoring and reset are functionality critical. Some specific use cases include:

• Embedded Systems: In embedded systems, the DS1815-5+ can be used to monitor the power supply of microcontrollers, ensuring that they reset properly in case of a power fluctuation or brownout condition.
• Industrial Control: For industrial control systems, the DS1815-5+ provides a reliable means of monitoring power supplies and ensuring that critical components reset correctly, preventing system failures and downtime.
• Telecommunications: In telecom equipment, the DS1815-5+ can be used to monitor power supplies for critical components, ensuring that the system remains stable and reliable even in the event of power supply issues.
• Consumer Electronics: In consumer electronics, the DS1815-5+ can be used to monitor power supplies for microprocessors and other critical components, ensuring that the system resets properly in case of power fluctuations.

Conclusion of DS1815-5+

The DS1815-5+ is a robust and reliable voltage supervisor IC that offers precise voltage monitoring and reset functionality. Its single-channel monitoring capability, combined with a 3.06V threshold and 100ms minimum reset timeout, makes it an ideal choice for a variety of applications where power supply stability is critical.
