ETA/钰泰 ETA6283V200FSG SOT-563 可编程限流负载开关

DESCRIPTION

ETA6283V200FSG is a load switch which provides full protection to systems and loads which may encounter large current conditions. ETA6283V200FSG 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. Current is prevented from flowing when the switch is off and the output voltage is higher than the input voltage. ETA6283 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 ETA6283 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.
