The Analog Devices LTC4226IUD-1#TRPBF is a dual Hot Swap controller IC that enables safe insertion and removal of two power paths from a live backplane or powered connector. Utilizing N-channel pass transistors, it supports supply voltages ranging from 4.5V to 44V with adjustable ramp-up rates.
Key features include selectable current limit ratios, a dual-rate fault timer for protection against overcurrent events, and selectable latchoff or auto-retry fault handling. The device is available in a 16-pin QFN (3mm x 3mm) package and operates within an ambient temperature range of -40°C to 85°C.
This controller is suitable for applications requiring safe board insertion into live backplanes, such as disk drives and rugged 12V/24V systems. It can also be configured as a bidirectional current limiter/circuit breaker and supports parallel power paths for high-current applications.
