MD1820K6-G

Overview

The MD1820K6-G is a high-speed, four-channel MOSFET gate driver manufactured by Microchip Technology. It features non-inverting outputs and operates within a supply voltage range of 4.5 V to 5 V. The device provides a peak output source and sink current of 2 A per channel. Electrical performance includes rise and fall times of 6 ns. It is housed in a 16-pin VQFN package with an operating temperature range from -20°C to +85°C.

Feature Summary

• High-speed switching capability with 6 ns rise and fall times for efficient power stage control
• Four independent channels providing simultaneous drive signals for multi-phase applications
• Non-inverting logic configuration simplifies interface with standard microcontroller or DSP outputs
• Robust 2 A peak output current capability ensures reliable driving of power MOSFET gates

Applications

• Motor control systems requiring precise phase timing
• Power supply inverters and DC-DC converters
• Industrial automation drives
• Battery management system switch control

Procurement Notes

Verify the specific suffix 'K6' corresponds to the required tape and reel packaging quantity of 3300 units. Confirm that the VQFN-16 package dimensions match the PCB footprint requirements. Ensure the operating temperature range of -20°C to +85°C meets the environmental specifications of the target application. Check RoHS compliance status if restricted substances are a concern.

Selection Notes

Select this component when non-inverting logic is required for the gate drive signal path. The 2 A peak current rating supports moderate-capacitance loads without external buffering. Consider the 4.5 V minimum supply voltage constraint against the available system rails. The single-supply architecture simplifies design compared to dual-supply drivers but requires careful attention to common-mode voltage levels.

Part Context

This part belongs to Microchip's dedicated gate driver family designed for power electronics. It complements other variants like the MD1812K6-G which may offer different pin configurations or inversion logic. The MD1820 series focuses on cost-effective, high-density solutions for industrial and consumer power applications using standard CMOS-compatible inputs.

Replacement Considerations

Direct substitutes include the MD1820 (without suffix) for loose tube stock or the MD1812K6-G if inverted outputs are acceptable. Verify pinout compatibility before swapping. No other Microchip parts share identical electrical characteristics and package simultaneously.
