Features & Applications

The MIC2545A-2YM TR is a part of MIC2545A 5.5 V integrated high-side power switches optimized for low loss DC power switching and other power management applications, including Advanced Configuration and Power Interface (ACPI)

The MIC2545A/49A is a cost-effective, highly integrated solution that requires few external components to satisfy USB and ACPI requirements. Load current management features include a precision,resistor-programmable output current-limit and a soft-start circuit, which minimizes inrush current when the switch is enabled

Features:

  • 2.7 V to 5.5 V input
  • Adjustable current-limit up to 3 A
  • Reverse current flow blocking
  • 90 μA typical on-state supply current
  • 1 μA typical off-state supply current
  • 50 mΩ maximum on-resistance
  • Open-drain fault flag
  • Thermal shutdown
  • Thermal shutdown output latch (MIC2549A)
  • 2ms (slow) soft-start turn-on, fast turnoff
  • Available with active-high or active-low enable

Applications:

  • USB power distribution
  • PCI Bus Power Switching
  • Notebook PC
  • ACPI power distribution
  • PC card hot swap applications
  • Inrush current-limiting
