LTC1726IS8-5#TRPBF - Triple Supply Monitor and µP Supervisor

The LTC1726IS8-5#TRPBF is a versatile triple supply monitor and microprocessor (µP) supervisory circuit designed to ensure the reliable operation of power-sensitive systems. Manufactured by Linear Technology, this component is engineered to monitor three supply voltages simultaneously, making it an ideal choice for systems that require precise power management and supervision.

This high-performance device features a fixed 5V monitor and two adjustable voltage monitors that can be set with external resistors. The LTC1726IS8-5#TRPBF is capable of monitoring voltages as low as 0.5V, which makes it suitable for low voltage applications. The adjustable thresholds provide the flexibility to tailor the monitoring capability to specific system requirements.

The LTC1726IS8-5#TRPBF includes a reset output that remains asserted for a minimum of 200ms after all the supply voltages have exceeded their respective reset thresholds. This provides a reliable reset signal to the µP, ensuring proper system initialization upon power-up or during a brownout condition. The reset logic is available in both active low and active high configurations, providing design versatility.

For enhanced system reliability, the LTC1726IS8-5#TRPBF features a manual reset input that allows an external signal to initiate a system reset. This can be particularly useful during system debugging or to recover from a software lock-up.

Designed for harsh environments, the LTC1726IS8-5#TRPBF operates over a wide temperature range from -40°C to +85°C. It is packaged in a compact 8-lead SOIC package, making it easy to integrate into space-constrained applications.

With its combination of multiple voltage monitoring, adjustable thresholds, and robust reset features, the LTC1726IS8-5#TRPBF is an excellent choice for system designers looking to enhance the reliability and performance of their power management systems. Whether used in computing, portable devices, or industrial applications, this component offers a high level of protection for critical system voltages.
