MIC2039AYM6-TR

The MIC2039AYM6 TR is a high-accuracy high-side adjustable current limit Power Switch providing increased system reliability by using 5% current limit accuracy. The switch has an operating input voltage range from 2.5 to 5.5V, is internally current limited and has thermal shutdown to protect the device and system. The MIC2039 is offered with either active-high or active-low logic level enable input controls. It has an open drain fault status output flag with a built-in 32ms delay that asserts low during over-current or thermal shutdown conditions. The switch features an adjustable output current limit that is resistor programmable from 0.2 to 2.5A. The switch also offers a unique, Kickstart feature that allows momentary high-current surges up to the secondary current limit (ILIMIT_2nd) during start-up or while operating in steady state. This is useful for charging loads with high inrush currents such as capacitors.

• Kickstart - momentary secondary current limit threshold
• Soft-start functionality
• Under-voltage lockout
