MAX4271ESA+
热插拔控制器, 2.7V至13.2V电源, NSOIC-8
产品概述
The MAX4271ESA+ is a 3V to 12V current limiting hot-swap controller with autoretry, dual speed/bilevel fault protection in 8 pin NSOIC package. This circuit breaker IC designed for hot-swap applications where line card is inserted into live backplane. Normally, when line card is plugged into live backplane, card's discharged filter capacitors provide low impedance that can momentarily cause main power supply to collapse. IC reside either in backplane or in removable card to provide inrush current limiting & short circuit protection. It includes many integrated features that reduce component count & design time. An onboard charge pump provides gate drive for a low cost, external n-FET. Integrated features like start-up current regulation, current glitch protection eliminate external timing resistors & capacitors. It has an open-drain status output to indicate fault condition & an adjustable overcurrent response time. It is used in base stations, RAID, ISDN, network route
- Supply voltage range is 2.7V to 13.2V
- Operating temperature range from -40°C to 85°C
- Provide safe hot swap for +3V to +12V power supplies with few external components
- Unique current regulation architecture minimizes n-FET linear mode duration
- Dual speed/bilevel current limit protects against current glitches and short circuits
- 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
- Features latched fault protection
