ETA6280

Programmable Current-Limited Load Switch

DESCRIPTION

FEATURES

The ETA6280 is a load switch which provides full

protection to systems and loads which may encounter

large current conditions. ETA6280 offers a 70mΩ current-

limited switch which can operate over an input voltage

range of 2.1-6V. The current limit can be externally

programmed by a precision resistor, ranging from 75mA to

2.2A. 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.

ETA6280 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 ETA6280

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

remain in the constant current mode indefinitely. The

nFAULT output asserts low during over-current and

reverse-voltage conditions.
