The LTC1646CGN#TR, manufactured by Analog Devices, Inc., is a Hot Swap controller designed for safely inserting and removing boards from live CompactPCI bus slots. This controller manages 3.3V and 5V supplies using two external N-Channel transistors, offering current limiting and programmable ramp-up rates.
Key features include dual-level electronic circuit breakers to protect supplies from overcurrent and short-circuit faults. It provides a PWRGD output to indicate when supply voltages are within tolerance and an OFF/ON pin for cycling power or resetting the circuit breaker. The PRECHARGE output can bias bus I/O pins during card insertion and extraction, while the LOCAL_PCI_RST# logic helps reset CPCI card logic if supply voltages are out of tolerance.
This device operates within a 2.7V to 7V input voltage range and features a circuit breaker threshold of 56mV with 16% typical accuracy. It is available in a 16-pin SSOP package suitable for surface mounting.
