A programmable current-limit threshold is offered between 400mA and 2.57A (typ) via an external resistor. Current-limit accuracy is ±10% @1A. The power-switch rise and fall times are controlled to minimize current surges during turn on/off. A constant-current mode is used when the output load exceeds the current-limit threshold. The DIO7552B/7553B limits the output current to a safe level by using a constant-current mode when the output load exceeds the current-limit threshold. An internal reverse voltage comparator disables the power switch when the output voltage is driven higher than the input to protect devices on the input side.
