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

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

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

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

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

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

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

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

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

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

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

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

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