ETA6021

Precision Load Switch with Adjustable Current Limit

DESCRIPTION

APPLICATION

The ETA6021 is a load switch which provides full protection

to systems and loads which may encounter large current

conditions. ETA6021 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. ETA6021

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 ETA6021 will

not turn off after a current limit fault, but will rather

remain in the constant current mode indefinitely.
