3 Description
The TPS2559-Q1 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-Q1
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-Q1.
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.

DESCRIPTION
Ground connection, connect externally to PowerPAD
Input voltage, connect a 0.1 μF or greater ceramic capacitor from IN to GND as close to the
IC as possible
Enable input, logic high turns on power switch.
External resistor used to set current-limit threshold; recommended. 24.9 kΩ ≤ R(ILIM) 100
kΩ.
Power-switch output
Active-low open-drain output, asserted during over-current or overtemperature conditions.
Internally connected to GND; used to heat-sink the part to the circuit board traces. Connect
PowerPAD to GND pin externally.
