ETA6281

Programmable Current-Limited Load Switch

DESCRIPTION

FEATURES

ETA6281 is a load switch which provides full protection to  Wide Input Voltage Range: 2.1V to 6V

systems and loads which may encounter large current  7.5V Input Standoff Voltage

conditions. ETA6281 offers a 70mΩ current-limited switch  6.1V OVP

which can operate over an input voltage range of 2.1-6V.  Up to 2.2A Max Load Current

The current limit can be externally programmed by a  Programmable Current Limit: 75mA to 2200mA

precision resistor, ranging from 75mA to 2.2A. Current is  Accurate Current Limit Threshold at 1.7A: +/-5%

prevented from flowing when the switch is off and the output  Fast Over Current Response

voltage is higher than the input voltage. ETA6281 also  Fault Flag Output: nFAULT Pin

features thermal shutdown protection which shuts off the  Reversed Input-Output Current Blocking

switch to prevent damage to the part when a continuous  Thermal Shutdown, UVLO Protection

over-current condition causes excessive heating. When the  Tiny SOT23-5, SOT23-6, DFN2x2-6 Package

switch current reaches the current limit, the parts operate in

a constant-current mode to prohibit excessive currents from

causing damage. The ETA6281 will not turn off after a

APPLICATIONS

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.

ETA6281 is available in three types of package: SOT23-5,

SOT23-6, DFN2x2-6.
