DescriptionThe 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 upto 1.5Aof continuous load current.
These devices offera programmable current-limit
threshold between 75 mA and 1.7A (typical) through external resistor. Current-limit accuracyas tightas
±6% can be achieved at the higher current-limit
settings. The power-switch rise and fall times are
controlledto minimize current surges during turnon
and turnoff.
TPS255x devices limit the output currenttoa safe
level by usinga 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
overcurrentor reverse-voltage situations. An internal
reverse-voltage comparator disables the power-
switch when the output voltageis driven higher than
the inputto protect devices on the input sideof the
switch. The FAULT output asserts low during
overcurrent and reverse-voltage conditions.
