LTC2919IMS-3.3#PBF - Precision Voltage Monitor

The LTC2919IMS-3.3#PBF is a high-accuracy voltage monitor designed by Linear Technology, now part of Analog Devices, to ensure the reliability and stability of power supplies in electronic systems. This precision voltage monitor is ideal for a wide range of applications, including system reset, power-on reset, power failure warning, and battery monitoring, among others.

Equipped with a fixed 3.3V threshold, the LTC2919IMS-3.3#PBF provides a precise monitoring solution for systems that require a stable 3.3V power supply. It is designed to maintain system integrity by monitoring the supply voltage and signaling when the voltage falls out of the predefined threshold range. This feature is critical for preventing data loss and hardware damage that could occur due to unexpected power fluctuations.

The device comes in a compact, surface-mount 10-lead MSOP package, making it suitable for space-constrained applications. Its small footprint allows for easy integration into various circuit designs without significantly impacting the overall size of the product.

Key features of the LTC2919IMS-3.3#PBF include:

• Fixed 3.3V threshold for monitoring a standard voltage supply.
• High accuracy with a tight threshold tolerance, ensuring reliable voltage monitoring.
• Low supply current, which helps to minimize the power consumption of the overall system.
• Guaranteed operation over the full temperature range of -40°C to 125°C, suitable for industrial and automotive applications.
• Multiple reset timeout periods available, allowing designers to choose the appropriate reset delay for their specific application.
• Internally compensated threshold voltage for stable operation over temperature and time.

The LTC2919IMS-3.3#PBF also features an adjustable reset timeout period, which can be set by an external capacitor. This flexibility allows designers to customize the reset timing to match specific system requirements. Additionally, the device offers both open-drain and push-pull reset outputs to interface with a variety of digital systems.

Overall, the LTC2919IMS-3.3#PBF is a robust and reliable solution for monitoring 3.3V power supplies, ensuring that electronic systems operate within their intended voltage parameters and providing peace of mind for engineers and product designers.
