MD1811K6-G

Overview

The MD1811K6-G is a high-speed quad MOSFET gate driver manufactured by Microchip Technology. It features four independent drivers in a 16-pin QFN package (4x4 mm). The device operates with a minimum supply voltage of 5 V and supports output currents up to 2 A. Signal transition times are specified at 6 ns for both rise and fall. It functions within an ambient temperature range of -20°C to +85°C, consumes 8 mA of quiescent current, and dissipates up to 2.2 W of power.

Feature Summary

• Integrates four independent high-speed gate drivers for simultaneous control applications
• Provides robust 2 A peak output drive capability for efficient MOSFET switching
• Utilizes a compact 16-lead QFN surface-mount package for space-constrained designs

Applications

• High-speed motor control systems requiring multi-phase driving
• Industrial power conversion circuits utilizing multiple MOSFET stages
• Automotive electronics demanding reliable gate drive performance

Procurement Notes

Verify the specific suffix 'G' indicates RoHS compliance status as per official documentation. Confirm the operating temperature grade corresponds to the commercial range (-20°C to +85°C) rather than extended industrial variants. Ensure the QFN-16 footprint matches the design layout requirements before procurement.

Selection Notes

Select this component when four isolated or semi-isolated gate outputs are required from a single IC. Compare against the MD1812K6-G if a wider supply voltage range starting at 4.5 V is necessary. Evaluate thermal dissipation capabilities given the 2.2 W power rating in the small QFN form factor.

Part Context

This part belongs to Microchip's family of high-speed quad MOSFET drivers. It complements other devices like the MD1812K6-G, differing primarily in supply voltage specifications and temperature ranges. These drivers are designed to interface directly with logic-level signals to drive power switches efficiently.

Replacement Considerations

The MD1812K6-G serves as a functional alternative with similar pinout but different electrical characteristics regarding supply voltage and temperature range. Verify compatibility with existing circuit constraints before substitution.
