LTC4223-1/LTC4223-2

Dual Supply Hot Swap

Controller for Advanced

Mezzanine Card

FEATURES

DESCRIPTION

The LTC^®4223 positive voltage Hot Swap^TMcontroller

allows a board to be safely inserted and removed from

a live AMC or MicroTCA backplane. It controls the main

12V supply with 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 also protected against short

circuit faults with a fast acting current limit and a 5%

accurate timed circuit breaker. The 3.3V output includes

both soft start and overcurrent protection.

Adjustable Response Time for Overcurrent Protection

Adjustable Supply Voltage Power-Up Rate

Thermal Shutdown Protection

LTC4223-1: Latch Off After Fault

LTC4223-2: Automatic Retry After Fault

16-Lead SSOP and 5mm × 4mm DFN Packages

■

The LTC4223 features 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 auxiliary 3.3V sup-

ply outputs. The LTC4223-1 features a latch-off circuit

breaker, while the LTC4223-2 provides automatic retry

after a fault.
