Pin Configuration
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.

Note:
1. Stresses greater than those listed under
MAXIMUM RATINGS may cause permanent
damage to the device. This is a stress rating only
and functional operation of the device at these or
any other conditions above those indicated in the
operational sections of this specification is not
implied. Exposure to absolute maximum rating
conditions for extended periods may affect
reliability.
2. The JEDEC high-K (2s2p) board used to derive
this data was a 3in × 3in, multilayer board with 1-
ounce internal power and ground planes and 2-
ounce copper traces on top and bottom of the board.
