3 Description

The TPS2560 and TPS2561 (TPS256x) are dualchannel

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.
