The demonstration circuit 1899A-A controls two independent power rail circuits each with Hot Swap? and ideal diode functionality provided by the LTC4228-1 dual ideal diode and Hot Swap controller. The DC1899A-A facilitates evaluation of LTC4228 performance in different operation modes such as supply ramp-up, power supply switchover, steady state, and over current faults. Power supply switchover mode can be realized as either an ideal diode or as a prioritizer.
- Power path and inrush current control for redundant supplies
- Low loss replacement for power schottky diodes
- Protects output voltage from input brownouts
- Allows safe hot swapping from a live backplane
- Controls N-Channel MOSFETs
- Limits peak fault current in <=1μs
- Adjustable current limit with circuit breaker
- Adjustable current limit fault delay
- Smooth switchover without oscillation
- 0.5μs ideal diode turn-on and turn-off time
- Status, fault and power good outputs
- Latch off after fault
