What are the key features of LTC1726EMS8-2.5#TRPBF?
- 3-channel voltage supervision with fixed 3.085V and 2.337V thresholds plus an adjustable channel covers multi-rail processor power supplies in one IC
- Programmable reset delay and integrated watchdog timer ensure orderly system startup and detect runaway firmware without external timing components
- Active-low, open-drain reset outputs allow wire-OR connection to multiple microprocessors or reset buses with flexible pull-up voltage selection
- Automotive-grade 8-pin MSOP package in tape-and-reel suits high-volume SMT assembly for vehicle ECU supervisor circuits
What is LTC1726EMS8-2.5#TRPBF used for?
The LTC1726EMS8-2.5#TRPBF is used in automotive electronic control units and industrial embedded systems where multiple processor supply rails at 3.3V and 2.5V must be individually supervised to ensure safe startup sequencing and fault detection. Its integrated watchdog timer with programmable reset delay prevents locked-up firmware from causing system failures without requiring a discrete watchdog IC, reducing BOM cost and PCB area. Multi-processor computing modules and FPGA-based systems that need coordinated reset assertion across 3 voltage domains benefit from the single-IC 3-channel supervision architecture.

Frequently Asked Questions
How does the LTC1726EMS8-2.5#TRPBF's 3-channel supervision simplify power sequencing in a dual-core processor design?
The LTC1726EMS8-2.5#TRPBF monitors 3 voltage rails simultaneously — with fixed thresholds at 3.085V and 2.337V plus one adjustable channel — and asserts all 3 active-low reset outputs if any rail drops below its threshold, ensuring that a dual-core processor system never enters an indeterminate state when one supply fails before the other during power sequencing.
What role does the programmable reset delay in the LTC1726EMS8-2.5#TRPBF play during system power-up in an automotive ECU?
The programmable reset delay holds the 3 reset outputs asserted for a configurable time after all monitored voltages exceed their thresholds, giving the automotive ECU's processor, Flash memory, and peripheral ICs sufficient time to stabilize and complete internal initialization before reset is released — preventing spurious glitches that could corrupt boot code or firmware state registers.
Can the watchdog timer in the LTC1726EMS8-2.5#TRPBF be used independently of the voltage supervision function?
Yes, the LTC1726EMS8-2.5#TRPBF's watchdog timer operates as a standalone function that the firmware must periodically reset within its programmable timeout window; if the firmware fails to toggle the watchdog input within the timeout period — indicating a firmware hang or infinite loop — the IC asserts the reset outputs to restart the processor, functioning independently of the 3-channel 2.337V to 3.085V voltage monitoring.
For a space-constrained automotive PCB, how does combining 3-channel supervision and watchdog in the LTC1726EMS8-2.5#TRPBF reduce component count versus discrete solutions?
Replacing 3 discrete voltage comparators, a watchdog timer IC, and a reset generator circuit with the single LTC1726EMS8-2.5#TRPBF in an 8-pin MSOP package reduces the component count by 5 to 8 parts and saves approximately 50mm² of PCB area, while the open-drain outputs allow bus-sharing with existing reset logic in the ECU without additional level-shifting buffers.
