LTC4226IMS-2#PBF, Hot-Swap Controller, 4.5 V to 44 V in, MSOP-16, -40°C to 85°C

Полупроводники - Микросхемы\Микросхемы Управления Питанием\Контроллеры Горячей ЗаменыLTC4226 is a dual hot swap™ controller allows two power paths to be safely inserted and removed from a live backplane or powered connector. Three selectable ratios of current limit to circuit breaker threshold accommodate noisy loads and momentary high peak currents without interruption, while a dual-rate fault timer protects the MOSFET from extended output overcurrent events. FAULT outputs indicate the circuit breaker status. This device can also be configured as a bidirectional current limiter/circuit breaker. For high current applications, two channels may be configured as parallel power paths. It is widely used in application such as apple firewire/IEEE 1394, disk drives, rugged 12V, 24V applications, hot board/connector insertion, uni/bidirectional current limiter/circuit breaker etc. • Wide operating voltage range is 4.5V to 44V• Optional auto-retry or latch off after overcurrent fault• High side drive for external N-channel MOSFET• Allows parallel power paths for High current applications• Fast response limits peak fault current• Auto-retry delay is 0.5s• Operating temperature is -40°C to 85°C• Packaging style is 16-lead plastic MSOP
