Key Features
- Dual-channel under/overvoltage monitoring with 2.5 V precision internal reference and adjustable thresholds for flexible multi-rail supervision
- 3 active-low open-drain reset outputs in a compact 8-pin TSOT-23 package, minimizing board area in space-constrained automotive and industrial designs
- Automotive-grade bipolar design with adjustable thresholds and <1% accuracy across -40°C to 125°C temperature range for reliable safety-critical power sequencing
Applications
The LTC2909CTS8-2.5#TRMPBF is used in automotive ECUs, ADAS modules, and industrial control boards requiring precise supervision of 2 independent power supply rails with over and undervoltage detection. Its 3 reset outputs support complex power-sequencing logic for multi-rail systems such as DSPs and FPGAs requiring sequenced startup. The 8-pin TSOT-23 package is ideal for space-constrained automotive electronics operating across the -40°C to 125°C range.

Frequently Asked Questions
How many supply rails can the LTC2909CTS8-2.5#TRMPBF monitor simultaneously and what is the internal reference voltage?
The LTC2909CTS8-2.5#TRMPBF monitors 2 independent supply rails simultaneously using a precision 2.5 V internal reference. Adjustable external resistor dividers set the trip thresholds for both under and overvoltage conditions, with 3 active-low open-drain reset outputs providing flexible fault signaling for each monitored rail and combined fault conditions.
What temperature range does the LTC2909CTS8-2.5#TRMPBF support and why is it suitable for automotive applications?
The LTC2909CTS8-2.5#TRMPBF operates from -40°C to 125°C, meeting the full automotive temperature grade requirement. Its bipolar design and automotive-grade qualification ensure threshold accuracy better than 1% across this range, which is critical for protecting ADAS sensors, ECU processors, and other safety-relevant automotive electronics from power supply faults.
How does the 8-pin TSOT-23 package of LTC2909CTS8-2.5#TRMPBF compare to larger supervisor packages for tight board layouts?
The 8-pin TSOT-23 package measures approximately 3 mm x 1.75 mm, making it one of the smallest housings available for a dual-rail supervisor with 3 outputs. Compared to larger SO-8 or DIP-8 equivalents, the TSOT-23 occupies roughly 70% less PCB area, enabling integration into dense automotive module designs where supervisor footprint is limited to under 6 mm².
