3 Description
The TPS2559 power-distribution switch is intended for
applications where a low resistance, precision current
limit switch is required or heavy capacitive loads are
encountered. The TPS2559 provides up to 5.5 A of
continuous load current with a precise current limit set
by a single resistor to ground. Output current is
maintained at a safe level by switching into a
constant-current mode when the output load exceeds
the current-limit threshold. During overload events the
output current is limited to the level set by R(ILIM). If a
persistent overload occurs, the device goes into
thermal shutoff to prevent damage to the TPS2559.
The power-switch rise and fall times are controlled to
minimize current surges during turn on or off. The
FAULT logic output asserts low during overcurrent or
overtemperature conditions.
