Linear Technology LTC1921CS8 - Dual Supply Monitor

The LTC1921CS8 from Linear Technology is a robust dual supply monitor designed to ensure the reliability and stability of electronic systems. This precision device is housed in a narrow 8-lead SOIC package, making it a compact solution for monitoring power supplies in a variety of applications.

The LTC1921CS8 is engineered to monitor two supply voltages simultaneously, offering a fixed threshold accuracy of ±1.5% over the entire operating temperature range. This high level of accuracy is critical for systems that require consistent and reliable operation, such as servers, computers, and industrial equipment.

One of the key features of the LTC1921CS8 is its low supply current, which is typically 30μA, making it an energy-efficient option for battery-powered devices. Additionally, the device has a wide operating temperature range from -40°C to 85°C, ensuring performance in harsh environments.

The LTC1921CS8 offers a reset output feature with both open-drain and push-pull configurations, providing flexibility in interfacing with other components of a system. The reset timeout period is adjustable using an external capacitor, which allows designers to customize the reset de-bounce timing to match specific system requirements.

For added versatility, the LTC1921CS8 can be used with a variety of supply voltages, with a minimum operating voltage of 1.2V and a maximum of 5.5V. This range makes it suitable for monitoring core and I/O voltages in modern low-voltage systems.

The combination of features such as tight threshold accuracy, low power consumption, adjustable reset timeout, and wide voltage range, makes the LTC1921CS8 an ideal choice for critical system monitoring applications. Its compact size and reliability are valuable for designers looking to enhance system integrity and protect against power supply failures.
