DEMO MANUAL DC2116A LTC4233/LTC4234 10A/20A Guaranteed SOA Hot Swap Controller Description Demonstration circuit 2116A features the LTC4233/ Configurable for Auto Retry or Latch Off for Overcurrent LTC 4234 10A/20A Guaranteed SOA Hot Swap Controllers. Faults The LTC4233 and LTC4234 are ideally suited for compact Power Good and Fault Outputs power distribution control in 2.9V to 15V applications for Available in 38-pin 5mm 9mm QFN packages, the hot board insertion protection, high side power switching, LTC4234 is showcased on DC2116A-A while the LTC4233 and electronic circuit breaker functions. They provide a rich is showcased on DC2116A-B, both configured for a 12V set of features to support Hot Swap applications including: application. By changing a few passive components, 2.9V 2.5% Accurate Undervoltage and Overvoltage Protection to 15V applications can easily be evaluated.
