Linear Technology LTC2904CDDB#TRMPBF Precision Dual Supply Monitors

The LTC2904CDDB#TRMPBF is a high-precision monitoring solution designed by Linear Technology, now part of Analog Devices, to ensure the reliable operation of dual supply systems. This advanced integrated circuit is engineered to monitor two supply voltages, typically in the range of 0.675V to 5.5V, making it an ideal choice for a wide array of applications, including portable devices, computers, and industrial systems where accurate power supply monitoring is critical.

Encased in a compact 8-lead DFN package, the LTC2904CDDB#TRMPBF offers a space-saving solution for systems where board real estate is at a premium. Its small footprint does not compromise its performance; the device boasts a tight 1.5% threshold accuracy over the entire operating temperature range of -40°C to 85°C. This precision ensures that the monitored supplies are kept within their intended operating ranges, thus safeguarding system stability and performance.

The LTC2904CDDB#TRMPBF features an adjustable reset timeout period, which can be configured by the user through an external capacitor. This flexibility allows designers to tailor the reset assertion time to the specific needs of their application. Additionally, the device offers a selectable reset threshold, providing further customization options for the voltage monitoring points.

One of the key benefits of the LTC2904CDDB#TRMPBF is its low power consumption. The device operates with a quiescent current of only 30µA, a critical feature for battery-powered applications where power efficiency is paramount. Furthermore, the product comes in a tape and reel package denoted by the #TRMPBF suffix, facilitating its use in automated manufacturing processes.

The LTC2904CDDB#TRMPBF also includes a manual reset input, allowing for a system reset to be triggered by an external event or user input. This feature enhances the system's controllability and can be used for routine system maintenance or in emergency situations.

In summary, the LTC2904CDDB#TRMPBF from Linear Technology is a versatile, precise, and efficient solution for dual supply voltage monitoring. Its compact design, adjustable features, and low power consumption make it an excellent choice for a wide range of applications where supply voltage integrity is essential.
