FEATURES
N N N N N N N N N USB Rev. 1.1 and 2.0 Compliant Four independent switches 2.7V to 5.5V input operation Low MOSFET ON resistance – IMP2524: 0.1Ω, 0.14Ω maximum – IMP2527: 0.2Ω, 0.3Ω maximum 500mA continuos load current per switch Low supply current – 110µA ON-state current, 0.75µA OFF-state current 1.25A maximum current limit, 750mA typical Thermal shutdown 2.4V undervoltage lockout (UVLO) Open-drain flag output – Undervoltage – Current limit – Thermal shutdown Output can be force higher than input Active HIGH(-1) and active LOW(-2) enable 16-pin SO and DIP packages, Die available Pin compatible with the Micrel MIC2524 and MIC2527 Quad USB High-Side Power Switch with Fault Detection Both device operate with voltage inputs from 2.7V to 5.5V The IMP2524/2527 conform to the new USB 1.1 standard. Fault current is limited to 750mA typically, and a flag output for each switch conveys fault information to the local USB controller. The IMP252x “Soft-Start” function ramps the ON-current to eliminate any excessive voltage drop on the input side that could occur when capacitive loads are charged.
