The PI5PD2560/2561 is dual-channel power-distribution
switch intended for applications where precision current
limiting is required or heavy capacitive loads and short
circuits are encountered. These devices offer a
programmable current-limit threshold between 250 mA
and 2.8A (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 PI5PD2560/2561 devices limit the
output current to a safe level by switching into a
constant-current mode when the output load exceeds the
current-limit threshold.
The FAULTx logic output for each channel
independently asserts low during over-current or over
temperature.
