MIC4128YML-TR

Overview

The MIC4128YML-TR is a dual low-side MOSFET gate driver manufactured by Microchip Technology. It operates within a supply voltage range of 4.5 V to 20 V and delivers a peak output current of 1.5 A for both sourcing and sinking. The device features independent inverting and non-inverting inputs, with typical rise and fall times of 20 ns and 18 ns respectively. It is housed in an 8-VDFN (3x3 mm) package with an exposed pad and supports an operating temperature range from -40 °C to +125 °C.

Feature Summary

• Dual channel configuration providing independent inverting and non-inverting drive outputs
• High-speed switching capability with nanosecond-level rise and fall times
• Low thermal impedance design utilizing an exposed pad for efficient heat dissipation

Applications

• Power management systems requiring low-side MOSFET control
• DC-DC converter topologies
• Motor control applications

Procurement Notes

Verify the specific suffix YML-TR to confirm the 8-VDFN (3x3 mm) package and tape-and-reel packaging format. Ensure compatibility with moisture sensitivity level requirements during storage and handling. Confirm that the lead-free status aligns with your assembly process specifications before finalizing procurement orders.

Selection Notes

Select this component when a compact dual-channel solution is required for low-side driving applications. The 8-VDFN package offers a small footprint suitable for space-constrained designs. Consider the 1.5 A output current capability to ensure adequate drive strength for the target MOSFET gates without external buffering components.

Part Context

This part belongs to the MIC4128 series of high-speed MOSFET drivers. It is designed as a cost-effective alternative to previous generations, maintaining performance while optimizing package size. The series is widely used in industrial and consumer power electronics where reliable switching and thermal management are critical.

Replacement Considerations

Check for MIC4128YME-TR if an SOIC-8 package is preferred over the VDFN form factor. Verify pinout compatibility and electrical parameters against any direct substitutes to ensure functional equivalence in the existing circuit design.
