Maxim Integrated MAX4273EEE
- Part Number:
- MAX4273EEE
- Manufacturer:
- Maxim Integrated
- Ventron No:
- 3256394-MAX4273EEE
- Description:
- IC CNTRLR HOT SWAP 16-QSOP
- ECAD Model:
-
- Datasheet:
- MAX4273EEE
Description
The MAX4271/MAX4272/MAX4273 are integrated 3V to 12V hot-swap controllers that enable safe insertion and removal of circuit cards into live backplanes. They regulate current to a preset limit during board insertion, preventing damage to connectors and components. After startup, DualSpeed/BiLevel protection safeguards against short circuits, load glitches, and overcurrent conditions. Fault recovery is handled by unlatching (MAX4271), autoretry (MAX4272), or programmed methods (MAX4273).
Features
Safe hot-swap for 3V to 12V power supplies with minimal external components
Unique current regulation architecture minimizes n-FET linear mode duration
Autoretry feature (MAX4272/MAX4273)
DualSpeed/BiLevel current limit protects against current glitches and short circuits
Power-on reset (MAX4273)
15V absolute maximum rating protects against inductive kickbacks during board removal
Internal charge pump generates gate drive for external n-MOSFET
Status output pin indicates fault/safe condition
Space-saving 8-pin SO, 16-pin QSOP packages
Applications
Base stations
RAID
Network routers and switches
Remote-access servers
ISDN
