Overview
The MIC4223YM is a dual low-side MOSFET gate driver manufactured by Microchip Technology. It features two independent inverting channels designed to drive N-channel power MOSFETs. The device operates with a supply voltage range of 4.5V to 18V and supports logic input levels of 0.8V (VIL) and 2.4V (VIH). It delivers a peak output current of 4A for both sourcing and sinking. Typical rise and fall times are 15ns, ensuring fast switching performance. The component is housed in an 8-SOIC package and is rated for operation over a junction temperature range of -40°C to 125°C.
Feature Summary
- Dual independent low-side driving configuration for N-channel MOSFETs
- Inverting logic input compatibility with standard TTL/CMOS levels
- High-speed switching capability with 15ns typical transition times
- Robust 4A peak source and sink output current capacity
Applications
- DC-DC converter synchronous rectification stages
- Motor control bridge circuits
- Power supply load switches
Procurement Notes
Verify the specific suffix 'YM' corresponds to the 8-SOIC package variant when ordering. Confirm that the application requires inverting logic inputs, as this driver does not support non-inverting signals. Ensure the PCB footprint matches the 8-SOIC dimensions and thermal requirements are met for the specified operating temperature range.
Selection Notes
Select this component when dual low-side driving is required with moderate current needs. It is suitable for applications where inverting signal paths are acceptable. Compare against non-inverting alternatives like the MIC4422 if signal phase preservation is critical. Verify that the 4A peak current meets the gate charge requirements of the target MOSFETs at the intended switching frequency.
Part Context
This part belongs to the MIC4223 series of high-speed MOSFET drivers. It is distinct from single-channel variants and non-inverting models within the same family. The YM designation specifically identifies the SOIC-8 package version, differentiating it from MSOP or other packaging options available in the broader product line.
Replacement Considerations
Direct functional substitutes include the MIC4223YMME for MSOP packaging or the MIC4422YM for single-channel non-inverting applications. Cross-referencing pinouts and logic inversion characteristics is essential before substitution.
