Overview
The MIC4128YMME-TR is a dual low-side MOSFET gate driver manufactured by Microchip Technology. It provides independent inverting and non-inverting outputs with a peak output current of 1.5 A. The device operates within a supply voltage range of 4.5 V to 20 V and supports logic input levels of 0.8 V (VIL) and 2.4 V (VIH). Typical rise and fall times are 20 ns and 18 ns, respectively. It functions reliably across an operating temperature range of -40°C to +125°C. The component is housed in an 8-pin MSOP package with an exposed pad for thermal management.
Feature Summary
- Dual channel configuration providing independent inverting and non-inverting drive signals
- High peak output current capability of 1.5 A for efficient MOSFET switching
- Integrated exposed pad design to enhance thermal dissipation performance
Applications
- Low-side power switching in motor control systems
- DC-DC converter gate drive stages
- General purpose power management circuits requiring isolated or complementary drive signals
Procurement Notes
Verify the specific suffix 'YMME' corresponds to the MSOP-8EP package variant rather than the standard SOIC-8 version. Confirm RoHS compliance status and Moisture Sensitivity Level (MSL 3) requirements for your assembly process. Ensure the ordering part number matches the exact pinout and thermal pad specifications required by your PCB layout.
Selection Notes
Select this component when a compact dual-channel solution with both inverted and non-inverted outputs is required. The MSOP-8EP package offers a smaller footprint compared to SOIC variants while maintaining similar electrical performance. Consider the 1.5 A drive strength sufficient for medium-power N-channel MOSFETs. Evaluate the thermal requirements of the application against the exposed pad's heat dissipation capabilities.
Part Context
This part belongs to the MIC4128 family of low-side gate drivers from Microchip Technology. It serves as a successor or alternative to Micrel-derived designs following the acquisition. The series focuses on providing robust gate drive solutions for power electronics applications where space constraints and drive efficiency are critical factors in system design.
Replacement Considerations
Direct substitutes include the MIC4128YME-TR for identical functionality in a different package format. Verify pin compatibility before replacing components to ensure proper interface alignment with existing circuitry.
