LINEAR LTC4223-1/4223-2 Manual(1)

Update: 28 September, 2023

The LTC4223 is a dual supply hot swap controller designed for Advanced Mezzanine Cards (AMC). It controls the main 12V supply using an external N-channel MOSFET and the 3.3V auxiliary supply with an integrated switch. The 12V output ramp rate is adjustable and includes inrush current limiting. The 12V output is protected against short circuit faults with a fast acting current limit and a 5% accurate timed circuit breaker. The 3.3V output features soft start and overcurrent protection. The LTC4223 provides a current monitor output for the 12V supply and reports fault and power-good status for both supplies. It also detects card presence and allows independent control of the 12V and 3.3V outputs. The LTC4223-1 features a latch-off circuit breaker, while the LTC4223-2 provides automatic retry after a fault.
