LTC2919CMS-3.3#PBF - Precision Voltage Supervisor

The LTC2919CMS-3.3#PBF is a high-accuracy voltage supervisor designed and manufactured by Linear Technology, now part of Analog Devices. This component is engineered to monitor over-voltage and under-voltage conditions, ensuring that electronic systems operate within their specified voltage ranges. It is an essential device for applications that require precise voltage monitoring to protect sensitive electronic circuits.

With a fixed threshold voltage of 3.3V, the LTC2919CMS-3.3#PBF is tailored for systems that utilize a 3.3V power supply rail. It offers a tight threshold accuracy of ±1.5% over the entire temperature range, which is critical for applications where voltage levels must be maintained with high precision.

The LTC2919CMS-3.3#PBF features an adjustable reset timeout period, which can be set by an external capacitor. This flexibility allows designers to tailor the supervisor's response time to the specific needs of their application. Additionally, the device offers a selectable reset timeout that provides either a 200ms minimum delay or an adjustable delay.

This voltage supervisor comes in a compact 10-lead MSOP package, making it suitable for space-constrained applications. It is designed to operate over a wide temperature range from -40°C to 125°C, ensuring reliable performance in various environments.

The LTC2919CMS-3.3#PBF also includes an array of features that enhance its functionality and ease of use. It has an input voltage range from 2.7V to 5.5V, making it compatible with a variety of power supply configurations. Furthermore, it provides a push-pull RESET output which eliminates the need for an external pull-up resistor, simplifying the design and reducing component count.

With its precision monitoring capabilities, the LTC2919CMS-3.3#PBF is an ideal choice for critical applications such as portable devices, automotive electronics, industrial control systems, and computer servers. Its robust feature set ensures that it can maintain the integrity of electronic systems by providing accurate and reliable voltage supervision.
