Product Description

Microchip MIC2039AYM6-TR is a high-side MOSFET power distribution switch designed to improve system reliability through precise current limit control and thermal protection. It is packaged in a compact 6-pin SOT-23 surface mount package measuring 3mm by 3mm, making it ideal for space-constrained electronic applications requiring efficient power switching.

This device operates from an input supply voltage range between 2.5V and 5.5V with an operating current typically around 300 μA. It incorporates a typical switch on resistance (RdsOn) of 75 milliohms at 5V, which reduces power loss and improves efficiency.

The MIC2039AYM6-TR provides ±5% current limit accuracy and includes protective features such as thermal shutdown and undervoltage lockout, ensuring operational safety during faults and preventing damage. A soft-start capability is included to control inrush current at device startup, complemented by a kickstart mode that permits a momentary higher current limit for 120 milliseconds.

The device offers a fast short-circuit response time of 10 microseconds for enhanced fault detection and supports logic-controlled enable signals, compatible with active-high or active-low logic levels. Its temperature operation spans from -40°C to +125°C, suitable for industrial and consumer electronics.

±5% current limit accuracy guarantees consistent performance. Wide input voltage range enables flexible power sources. Low quiescent current supports energy-efficient designs. Thermal shutdown protects against overheating scenarios.

Compact surface mount design simplifies PCB layouts. Soft-start and kickstart features provide controlled power delivery. Fast short-circuit response enhances system safety. Logic controlled enable pin supports versatile control options.

Operating temperature range suitable for harsh environments. Pin compatible with MIC2009 and MIC2019 for design flexibility.

Applications for the MIC2039AYM6-TR include power management in consumer electronics, industrial automation systems, communication equipment, and automotive electronic modules. Its robust design and integrated protections make it a dependable component in power distribution circuits.
