TPS2553DBVR-1 =ETA6020
The ETA6020 is a load switch which provides full protection
to systems and loads which may encounter large current
conditions. ETA6020 offers a 95mΩ current-limited switch
which can operate over an input voltage range of 2.5-5.5V.
The current limit can be externally programmed by a
precision resistor, ranges from 75mA to 1.7A. Switch control
is by a logic input (EN) capable of interfacing directly with
low voltage control signals. Current is prevented from
flowing when the switch is off and the output voltage is
higher than the input voltage. ETA6020 also features
thermal shutdown protection which shuts off the switch to
prevent damage to the part when a continuous over-current
condition causes excessive heating. When the switch current
reaches the current limit, the parts operate in a constantcurrent
mode to prohibit excessive currents from causing
damage. The ETA6020 will not turn off after a current limit
fault, but will rather remain in the constant current mode
indefinitely. The n FAULT output asserts low during overcurrent
and reverse-voltage conditions.
ETA6020 is housed in a tiny DFN2x2-6L package
