3 Description
The TPS255x and TPS255x-1 power-distribution
switches are intended for applications where
precision current limiting is required or heavy
capacitive loads and short circuits are encountered
and provide up to 1.5 A of continuous load current.
These devices offer a programmable current-limit
threshold between 75 mA and 1.7 A (typical) through
an external resistor. Current-limit accuracy as tight as
±6% can be achieved at the higher current-limit
settings. The power-switch rise and fall times are
controlled to minimize current surges during turnon
and turnoff.
TPS255x devices limit the output current to a safe
level by using a constant-current mode when the
output load exceeds the current-limit threshold.
TPS255x-1 devices provide circuit breaker
functionality by latching off the power switch during
overcurrent or reverse-voltage situations. An internal
reverse-voltage comparator disables the power-
switch when the output voltage is driven higher than
the input to protect devices on the input side of the
switch. The FAULT output asserts low during
overcurrent and reverse-voltage conditions.
