MAX5920AESA+

The MAX5920AESA+ is a -48V hot-swap controller with external Rsense in 8 pin NSOIC package. The hot swap controller allows a circuit card to be safely hot plugged into a live backplane. This controller provides a controlled turn-on to circuit cards preventing glitches on the power-supply rail and damage to board connectors and components. It provide under voltage, overvoltage and overcurrent protection and ensure input voltage is stable and within tolerance before applying power to the load. It protects a system against overcurrent and short circuit conditions by turning off the external MOSFET in the event of a fault condition. It also provides protection against input voltage steps. Typical applications include telecom line cards, network switches/routers, central-office line cards, server line cards and base station line cards.

• Operates from -20V to -80V, well-suited for -48V power systems
• Operating temperature range from -40°C to 85°C
• Allows safe board insertion and removal from a live -48V backplane
• Pin and function compatible with LT4250L, pin-compatible with LT1640L
• Circuit breaker immunity to input voltage steps and current spikes
• Withstands -100V input transients with no external components
• Programmable inrush and short circuit current limits
• Powers up into a shorted load
• Power good control output
• Thermal shutdown protects external MOSFET
• Base-Station Line Cards; Central-Office Line Cards; Network Routers and Switches; Server Line Cards; Telecom Line Cards
