MIC2019YM6

Overview

The MIC2019YM6 is a P-channel power switch from the MIC2019 family, manufactured by Microchip Technology. It operates with a load voltage range of 2.5V to 5.5V and supports a maximum output current of 900mA. The device features an adjustable current limit and thermal shutdown protection. It has a typical on-resistance of 170 milliohms and uses a non-inverting open/switch interface. The component is housed in a SOT-23-6 surface-mount package and functions as a high-side switch without requiring a separate supply voltage.

Feature Summary

• Integrates adjustable current limiting and thermal shutdown for robust fault protection
• Utilizes a non-inverting control interface for straightforward logic compatibility
• Provides low on-resistance performance to minimize conduction losses

Applications

• High-side switching for peripheral power distribution
• Load driver applications in portable electronics
• Power management circuits requiring overcurrent protection

Procurement Notes

Verify the specific suffix against official documentation to confirm exact packaging and tape-and-reel specifications. Ensure the procurement channel sources directly from authorized distributors to guarantee authenticity. Confirm RoHS compliance status matches project requirements before finalizing orders.

Selection Notes

Select this component when a high-side P-channel switch with integrated protection is required within a 5.5V system. Consider the SOT-23-6 package constraints for PCB layout. Evaluate the 900mA current rating against peak load demands to ensure adequate headroom for reliable operation.

Part Context

This part belongs to the MIC2019 family of single-channel power switches. It serves as a compact solution for managing power delivery in space-constrained designs. The device integrates control logic and protection circuitry into a small footprint, simplifying system architecture compared to discrete solutions.

Replacement Considerations

Consult the official datasheet for direct pin-compatible alternatives within the same family. Verify that any substitute maintains identical voltage ratings and protection features.
