Vishay / Siliconix SiP32419/29 28V Load Switches

Vishay Siliconix SiP32419/29 28V Load Switches are load switches that integrate multiple control features, which simplify the design and increase the reliability of the circuitry connected to the switch. Both devices are 56mΩ switches designed to operate in the 6V to 28V range. An internally generated gate drive voltage ensures good RON linearity over the input voltage operating range. The Vishay Siliconix SiP32419/29 has a slew rate control circuit that controls the switch turn-on time to the value set by an external capacitor. These devices feature a low voltage control logic interface that can be controlled without the need for level shifting. These devices also include a Power Good flag.

Features

  • 6V to 28V operation
  • Programmable soft-start
  • Programmable current limit
  • Over temperature protection
  • ON resistance 56mΩ
  • Power Good, when VOUT reaches 90% of VIN
  • Fault flag
  • 4.8V/5.4V (typ./max.) under-voltage lockout
  • DFN10 3mmx3mm package 
  • SiP32429 will turn OFF the switch under fault conditions and re-try to turn on through the full soft-start procedure 150ms after the switch is off and the fault removed
  • SiP32419 will turn OFF the switch under fault conditions and remain OFF

Applications

  • Personal computers
  • Lighting
  • Flat-panel displays
  • Game consoles
  • Industrial
  • Network communication
  • Data storage
