The LTC1921CMS8#TRPBF by Analog Devices is a dual power supply monitor designed for critical power applications. It independently monitors two independent –48V supplies, including their fuses, and drives optoisolators to indicate status, adhering to standard backplane specifications.
This device features dual supply overvoltage and undervoltage detection circuits with preset trip thresholds that are guaranteed over temperature. It ignores fast supply transients, preventing false detections. The LTC1921CMS8 operates from –10V to –80V with a low typical power dissipation of less than 10mW.
Key specifications include undervoltage faults at –38.5V ±1V MAX, overvoltage faults at –70V ±1.5V MAX, and undervoltage recovery at –43V ±0.5V MAX. It also tolerates DC faults to –100V and accidental supply reversal to 100V.
The LTC1921CMS8 is available in a small footprint 8-lead MSOP package, making it suitable for space-constrained designs. It is specified for operation from –40°C to 85°C. Applications include telecom and networking backplanes, and high voltage fuse monitoring.
The operating voltage range is -10V to -80V.
It is available in an 8-MSOP surface mount package.
The operating temperature range is -40°C to 85°C.
Undervoltage fault threshold is -38.5V ±1V maximum, overvoltage fault threshold is -70V ±1.5V maximum.
Yes, it withstands transient voltages up to 200V and -200V.
Typical power dissipation is 10mW.
