rise and fall times are controlled to m inimize current surges during turn on a nd off. Each channel of the TPS256x de vices limit the output current to a saf e level by switching into a constantcur rent mode when the output load exceeds the current-limit threshold. The FAULTx logic output for each channel independ ently asserts low during overcurrent an d overtemperature .

3 Description
The TPS2560 and TPS2561 (TPS256x) are dual-
channel power-distribution switches 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 2.8 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 constant-
current 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.
