DESCRIPTION
The TPS2561-Q1 is a 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 2.8 A (typ) per channel through an
external resistor. The power-switch rise and fall times
are controlled to minimize current surges during turn
on or off.
Each channel of the TPS2561-Q1 device limits 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 over temperature conditions.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

(1) Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating
conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) Voltages are referenced to GND unless otherwise noted.
(3) Surges per EN61000-4-2, 1999 applied between USB and output ground of the TPS2561EVM (HPA424) evaluation module
