Linear Technology LTC1921IMS8#PBF
- Part Number:
- LTC1921IMS8#PBF
- Manufacturer:
- Linear Technology
- Ventron No:
- 3267700-LTC1921IMS8#PBF
- Description:
- IC DUAL PWR SUPPLY MONITOR 8MSOP
- ECAD Model:
-
- Datasheet:
- LTC1921IMS8#PBF
Description
The LTC1921 is a dual-48V supply and fuse monitor that independently monitors two -48V supplies and their fuses. It drives up to three optoisolators to indicate status in accordance with standard backplane specifications. The LTC1921 requires only three noncritical resistors and optoisolators, replacing multiple voltage comparators, a voltage reference, and several precision resistors.
Features
Withstands transient voltages up to 200V/-200V
Requires no precision external components
Independently monitors two -48V supplies for:
Undervoltage faults: -38.5V ±1V MAX
Overvoltage faults: -70V ±1.5V MAX
Accurately detects undervoltage fault recovery: -43V 0.5V MAX
Monitors two external fuses
Operates from -10V to -80V
Tolerates DC faults to -100V
Tolerates accidental supply reversal to 100V
Small footprint: 8-lead MSOP package
Specified from -40°C to 85°C
Applications
Telecom backplanes or switch cards
Networking backplanes or switch cards
High voltage fuse monitoring
