LTC2903CS6-D1#TRMPBF - Precision Quad Supply Monitor

The LTC2903CS6-D1#TRMPBF is a high-performance, precision quad supply monitor designed and manufactured by Linear Technology, a leader in analog integrated circuits. This compact, feature-rich device is ideal for system monitoring and provides reliable protection for CPUs, FPGAs, and other digital systems that require voltage supply supervision to ensure proper operation.

Encased in a small 6-lead TSOT-23 package, the LTC2903CS6-D1#TRMPBF offers a space-saving solution for monitoring up to four supply voltages simultaneously. This is particularly useful in systems where board space is at a premium and multiple supply voltages need to be tracked with precision.

The device is capable of monitoring positive voltages as low as 0.675V and up to 5.5V without the need for external resistive dividers, simplifying the design and reducing component count. The LTC2903CS6-D1#TRMPBF features a tight 1.5% threshold accuracy over the entire operating temperature range of -40°C to 85°C, ensuring reliable performance in a wide range of environmental conditions.

One of the standout features of this supply monitor is its flexibility. The LTC2903CS6-D1#TRMPBF can be configured to monitor a combination of 2.5V, 3.3V, and 5V supplies with one adjustable input, allowing for custom voltage thresholds via an external resistive divider. This versatility makes it an excellent choice for a broad range of applications, including portable devices, telecommunications, and industrial equipment.

The device also includes a manual reset input, which provides an external override of the reset output for system debugging purposes. Additionally, the reset output is guaranteed to be in the correct state for VCC down to 1V, ensuring the system can recover from brownout conditions effectively.

For ease of integration, the LTC2903CS6-D1#TRMPBF is available in a tape and reel package, ready for automated manufacturing processes. With its combination of precision, flexibility, and compact size, the LTC2903CS6-D1#TRMPBF is a reliable solution for voltage monitoring in critical applications where system integrity cannot be compromised.
