MIC2015-1.2YM6

Overview

The MIC2015-1.2YM6 is a single high-side power distribution switch manufactured by Microchip Technology. It operates within a supply voltage range of 2.5V to 5.5V and supports a continuous load current of 1.2A with an on-resistance of 70mΩ. The device features fixed current limiting, active-high control logic, and Kickstart functionality for inductive loads. It is housed in a compact SOT-23-6 surface-mount package and functions reliably across an extended temperature range of -40°C to +85°C.

Feature Summary

• Integrated fixed current limit protection prevents damage during overload conditions
• Kickstart circuit provides enhanced drive capability for inductive loads
• Active-high enable input simplifies digital interface integration
• Low on-resistance minimizes power dissipation and heat generation

Applications

• Digital television (DTV) power management
• Set-top box (STB) peripheral switching
• Printer power distribution circuits
• Personal digital assistant (PDA) battery protection

Procurement Notes

Verify the complete part number including suffixes such as TR for reel packaging against official Microchip documentation. Confirm that the SOT-23-6 package variant matches your board layout requirements. Ensure the operating temperature range aligns with your system's environmental specifications before finalizing procurement orders.

Selection Notes

Select this component when a single-channel high-side switch with integrated current limiting is required for low-voltage applications. The 1.2A rating suits moderate load scenarios where space efficiency is critical. Consider the 70mΩ on-resistance for thermal management calculations in enclosed designs requiring minimal external components.

Part Context

This device belongs to the MIC20XX series of power distribution switches designed for portable and consumer electronics. The series offers various current ratings and package options to accommodate different power requirements while maintaining a small footprint suitable for dense PCB layouts in modern electronic devices.

Replacement Considerations

Consult Microchip datasheets for direct pin-compatible alternatives within the MIC20XX family. Verify electrical parameters such as current limits and on-resistance match your design constraints before substituting with other manufacturers' high-side switches.

FAQ

What is the function of the Kickstart feature?

Kickstart provides a temporary boost in gate drive current to rapidly discharge capacitive or inductive loads, ensuring fast turn-on times.

How does the device handle overcurrent conditions?

The MIC2015-1.2YM6 employs fixed current limiting to restrict output current to 1.2A, protecting both the switch and the load from damage during short circuits or overloads.
