high side load switchMicrel, Inc. (San Jose, CA) introduced the MIC94161/62/63/64/65; a family of high-side load switches with low on resistance (14.5 mΩ) capable of delivering up to 3 A of continuous current in a small 1-mm x 1.5-mm wafer level chip-scale package. These small devices feature true reverse current protection with a wide input voltage range of 1.7 V to 5.5 V. This makes appropriate for low power or space-constrained applications such as smart phones, tablets, mobile computers, set top boxes, and solid state drives. Other features include:

  • An active pull-down circuit (MIC94162/MIC94164) that discharges the output capacitors when the device is turned off
  • Internal soft start function (MIC94161/MIC94164/MIC94165) that reduces in-rush input current and input over voltage protection (MIC94161). 
  • Operation from -40ºC to +125ºC.
