一,产品概述(General Description)     3T5嘉泰姆


     The CXUS7701H/L SmartSwitch is a current limited P-channel MOSFET power 3T5嘉泰姆

switch designed for high-side load switching applications. This switch operates 3T5嘉泰姆

with inputs ranging from 2.4V to 5.5V, making it ideal for both 3V and 5V systems. An integrated current-limiting circuit protects the input supply against large currents 3T5嘉泰姆

which may cause the supply to fall out of regulation. The CXUS7701H/L is also 3T5嘉泰姆

protected from thermal overload which limits power dissipation and junction 3T5嘉泰姆

temperatures. It can be used to control loads that require up to 1A. Current limit 3T5嘉泰姆

threshold is programmed with a resistor from SET to ground. The quiescent supply3T5嘉泰姆

 current is typically a low 9μA. In shutdown mode, the supply current decreases3T5嘉泰姆

 to less than 1μA.3T5嘉泰姆

      The CXUS7701H/L is available in a Pb-free 5-pin SOT23 or 8-pin SC70JW package3T5嘉泰姆

 and is specified over the -40°C to +85°C temperature range.3T5嘉泰姆

七,功能概述3T5嘉泰姆

Operation in Current Limit3T5嘉泰姆

     When a heavy load is applied to the output of the CXUS7701H/L,the load current is limited to the value of ILIM determined by RSET. See Figure 2, "Overload Operation." Since 3T5嘉泰姆

the load is demanding more current than ILIM, the voltage at  the output drops. This causes the CXUS7701H/L to dissipate a larger than nor-mal quantity of power, and its die temperature to increase. When the die temperature exceeds an over-temperature limit, the CXUS7701H/L will shut down until is has cooled sufficiently, at which point it will startup again.3T5嘉泰姆

      The CXUS7701H/L will continue to cycle on and off until the load is removed, power is removed, or until a logic  high level is applied to ON. 3T5嘉泰姆

Enable Input3T5嘉泰姆
    In many systems, power planes are controlled by integrated circuits which run at lower voltages than the power plane itself. The enable input ON of the CXUS7701H/L has low and high threshold voltages that accommodate this condition.The threshold voltages are compatible with 5V TTL and 2.5V to 5V CMOS. 3T5嘉泰姆

Reverse Voltage3T5嘉泰姆
      The CXUS7701H/L is designed to control current flowing from IN to OUT. If a voltage is applied to3T5嘉泰姆

 OUT which is  greater than the voltage on IN, large currents may flow. This could cause damage to the3T5嘉泰姆
