The cPC2PMC uses a Linear Technology LTC Hot Swap controller that allows the cPC2PMC to be safely inserted and removed from a live CompactPCI slot. Four external transistors control the 3.3V, 5V, 12V and -12V supplies. All supply voltages are ramped up at a controlled rate to prevent any current glitches. An electronic circuit breaker protects all four supplies against overcurrent faults. The foldback current limit feature limits current spikes and power dissipation when shorts occur and the cPC2PMC to be powered up without tripping the circuit breaker.
Features Allows safe board insertion and removal from a live CompactPCI slot.
Controls 3.3V, 5V, 12V, -12V supplies. Foldback current limit with circuit breaker. Ramped supply voltage power-up. Fault and power-good outputs. A change of state in the microswitch will occur during an insertion and extraction from a CompactPCI backplane.
