What are the key features of LTC1326IMS8#PBF?
- Triple-channel voltage supervisor monitors 3 independent supply rails simultaneously with a precision 4.725 V reset threshold for accurate 5 V supply fault detection
- Manual push-button reset input allows operator-initiated system reset independent of supply voltage conditions, essential for embedded and industrial control panels
- Compact 8-pin MSOP (PDSO-G8) package with fixed reset threshold eliminates external resistor dividers, simplifying PCB design and reducing component count by 6 passives
What is LTC1326IMS8#PBF used for?
The LTC1326IMS8#PBF is used in embedded processor systems that require simultaneous monitoring of 3 power supply rails such as 5 V, 3.3 V, and 1.8 V, issuing a reset signal if any rail falls below its threshold. It is well suited for industrial controllers, PLC modules, and communication equipment where reliable system startup and orderly shutdown under brownout conditions are critical. The manual push-button reset input also makes it appropriate for instrumentation panels and test equipment where field operators need a hardware reset capability independent of software.

Frequently Asked Questions
How many supply rails does the LTC1326IMS8#PBF monitor, and what is its reset threshold voltage?
The LTC1326IMS8#PBF monitors 3 independent supply channels simultaneously. Its reset threshold voltage is precisely set at 4.725 V, making it optimized for detecting undervoltage faults on 5 V power rails. When any monitored rail drops below its threshold, the IC asserts a reset output that holds the system microprocessor in reset for a programmable timeout period, preventing erratic operation during supply brownouts below 4.75 V.
What does the manual push-button reset input on the LTC1326IMS8#PBF enable in industrial panel designs?
The manual push-button reset input allows an operator to assert a hardware system reset without cycling power, independent of whether any monitored supply has failed. In industrial HMI panels and factory automation controllers, this means a technician can reset a hung microprocessor by pressing a front-panel button, triggering a clean reset pulse of at least 200 ms. This is critical for 24/7 production systems where power cycling would disrupt connected field devices on 4-20 mA process loops.
How does using the LTC1326IMS8#PBF in an 8-pin MSOP package simplify PCB layout compared to discrete reset circuits?
A discrete reset circuit monitoring 3 rails requires at least 6 resistors, 3 comparators, and 3 capacitors occupying over 100 mm² of PCB area. The LTC1326IMS8#PBF integrates all 3 supervisors in an 8-pin MSOP footprint of approximately 15 mm², a reduction of more than 85%. It also eliminates the resistor tolerance stack-up error that degrades threshold accuracy beyond ±5% in discrete designs, achieving ±1% threshold accuracy internally.
When should an engineer choose the LTC1326IMS8#PBF over a single-channel supervisor like the MAX809 for a multi-rail embedded system?
An engineer should choose the LTC1326IMS8#PBF when the design has 3 or more critical supply rails, each needing independent undervoltage monitoring below its nominal voltage, and a manual reset button is required. For a system with 5 V analog, 3.3 V digital, and 1.8 V I/O rails, using 3 separate MAX809 single-channel supervisors requires 3 ICs, 3 footprints, and 3 reset signals — whereas the LTC1326 consolidates monitoring into 1 IC with a single 8-pin MSOP, reducing board space by over 60%.
