SP2525A-1EN-L/TR 电源开关 IC

SP2525A-1EN-L/TR

电源开关 IC - 配电 3-5V USB PWR CNTRL SWITCH -40-85C Single Channel USB Power Distribution Switch

GENERAL DESCRIPTION  

The SP2525A-1EN-L/TR SP2525A device is an integrated high-side  power switch ideal for self-powered and buspowered  Universal Serial Bus (USB)  applications.

The high-side switches are MOSFETs with  70mΩ RDS(ON), which meets USB voltage drop  requirements for maximum transmission wire  length. Multi-purpose open-drain fault flag  output indicates over-current limiting, thermal  shutdown, or under voltage lockout. Output  current is typically limited to 0.85A below the  5A safety requirement, and the thermal  shutdown function shuts the switch off to  prevent damage under overcurrent conditions.  Guaranteed minimum output rise time limits  inrush current during hot plug-in, minimizing  EMI and preventing the voltage at the  upstream port from dropping excessively.
