These devices offer a programmable current-limit threshold between 250 mA and 2.
8 A (typ) per channel through an external resistor.
The power-switch rise and fall times are controlled to minimize current surges during turn on and off.
Each channel of the TPS256x devices limit the output current to a safe level by switching into a constantcurrent mode when the output load exceeds the current-limit threshold.
The FAULTx logic output for each channel independently asserts low during overcurrent and overtemperature conditions.
