一,产品概述(General Description)      k5b嘉泰姆

      The CXLS4261 CXLS4262 is a load switch which provides full protection to systems and loads which k5b嘉泰姆

may encounter large current conditions. CXLS4261 CXLS4262 offers a 95mΩ current‐limited switch which can k5b嘉泰姆

operate over an input voltage range of 2.5‐5.5V. The current limit can be externally programmed k5b嘉泰姆

by a precision resistor, ranges from 75mA to 1.4A.Switch control is by a logic input (EN) capablek5b嘉泰姆

 of interfacing directly with low voltage control signals. Current is prevented from flowing when k5b嘉泰姆

the switch is off and the output voltage is higher than the input voltage. CXLS4261 CXLS4262 also featuresk5b嘉泰姆

thermal shutdown protection which shuts off the switch to prevent damage to the part when acontinuous k5b嘉泰姆

over‐current condition causes excessive heating. When the switch current reaches the current limit,k5b嘉泰姆

the parts operate in a constant‐current mode to prohibit excessive currents from causing damage. k5b嘉泰姆

The CXLS4261 CXLS4262 will not turn off after a current limit fault, but will rather remain in the constant k5b嘉泰姆

current mode indefinitely. The nFAULT output asserts low during over‐current and reverse‐voltage conditions. k5b嘉泰姆

   CXLS4261 CXLS4262 is housed in a tiny DFN2x2‐6L packagek5b嘉泰姆
