These devices offer a programmable current-limit threshold between 500 mA and 5A (typ) per channel via an external resistor. The power-switch rise and fall times are controlled to minimize current surges during turn on/off. Each channel of the PI5PD2556/2557 devices limits the output current to a safe level by switching into a constant-current mode when the output load exceeds the cur...
