ETA6024

Precision Load Switch with Adjustable Current Limit

DESCRIPTION

APPLICATION

The ETA6024 is a load switch which provides full protection

to systems and loads which may encounter large current

conditions. ETA6024 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. ETA6024 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 constant-

current mode to prohibit excessive currents from causing

damage. The ETA6024 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 over-

current and reverse-voltage conditions.
