MIC94063BC6-TR

Overview

The MIC94063BC6-TR is a high-side power switch manufactured by Microchip Technology, formerly Micrel. It features a P-channel MOSFET architecture housed in an SC-70-6 package. The device supports a maximum output current of 2A with a typical on-resistance (Rds On) of 77mOhm. Key electrical characteristics include non-inverting input logic and a controlled slew rate to minimize inrush current. It integrates load discharge functionality for safe power-down sequences.

Feature Summary

• Integrated load discharge circuitry for controlled power-off
• Slew rate control to limit inrush current during turn-on
• Non-inverting logic interface for simple drive requirements

Applications

• Portable electronic devices requiring efficient power distribution
• Battery-powered systems needing low quiescent current management
• Peripheral load switching in consumer electronics

Procurement Notes

Verify the manufacturer origin, as the component was originally produced by Micrel Semiconductor before acquisition by Microchip Technology. Confirm the specific suffix (-TR) indicates tape-and-reel packaging if required for automated assembly. Ensure the datasheet version matches the production date code to guarantee parameter accuracy, particularly regarding Rds On and thermal performance specifications.

Selection Notes

Select this component when a compact high-side switch with integrated load discharge is required. The SC-70-6 package suits space-constrained designs. Consider the 2A current limit and 77mOhm on-resistance for efficiency calculations. The non-inverting input simplifies control logic compared to inverting alternatives. Evaluate thermal dissipation capabilities based on the PCB copper area available for heat spreading.

Part Context

This part belongs to the MIC9406x series of high-side power switches from Microchip/Micrel. These components are designed for portable applications where power efficiency and small footprint are critical. The series typically includes variants with different current ratings and packages, such as SOT-363 or TSSOP, offering flexibility for various load driver needs in mobile and battery-operated equipment.

Replacement Considerations

Check for direct pin-compatible substitutes within the MIC9406x family, such as the MIC94064, which may offer similar features with slight parameter variations. Verify that any replacement maintains the same SC-70-6 package and electrical characteristics, specifically the 2A current rating and non-inverting logic, to ensure circuit compatibility without redesign.
