DC интеллектуальные ключи MIC2545A-1YM

Аналоговый переключатель , 0.035 Ом, SOP, 8 вывод(-ов)

The MIC2545A-1YM is a programmable current-limit high-side Analog Switch for low-loss DC power switching and other power-management applications, including advanced configuration and power interface (ACPI). It 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. Thermal shutdown, along with adjustable current limit, protects the switch and the attached device. The MIC2545A's open-drain flag output is used to indicate current-limiting or thermal shutdown to a local controller.

• Adjustable current-limit up to 3A
• Reverse current flow blocking
• Open-drain fault flag
• Thermal shutdown 2ms (slow) Soft-start turn-on, fast turnoff
• 90µA Typical on-state supply current
• 1µA Typical off-state supply current
