TPS25990 incorporates four levels of protection against overcurrent:

1. Adjustable slew rate (dVdt) for inrush current control
2. Active current limit with an adjustable threshold (I_LIM) for overcurrent protection during start-up
3. Circuit-breaker with an adjustable threshold (I_OCP) and blanking timer (t_{OC_TIMER}) for overcurrent protection during steady-state
4. Fast-trip response to severe overcurrent faults with a programmable threshold to quickly protect against severe short-circuits under all conditions, as well as a fixed threshold (I_FFT) during steady state
