Overview
The MIC4451YM is a low-side MOSFET gate driver manufactured by Microchip Technology, housed in an 8-pin SOIC package. It features an inverting configuration with a peak output current of 12 A and operates within a supply voltage range of 4.5 V to 18 V. The device exhibits rise and fall times of 25 ns, with maximum on/off delays of 80 ns. It functions at temperatures from -40°C to +85°C, consumes 450 µA of quiescent current, and utilizes CMOS logic.
Feature Summary
- Delivers high peak output current capability for efficient switching
- Provides fast transition times for high-speed operation
- Features inverting logic configuration for signal control
Applications
- Low-side MOSFET switching applications
- High-speed power conversion circuits
- Industrial motor drive systems
Procurement Notes
Verify the specific suffix 'YM' corresponds to the 8-SOIC 3.90mm tube packaging variant. Confirm RoHS compliance status through official documentation. Ensure the inverting logic type matches system requirements. Check humidity sensitivity handling procedures during storage and assembly.
Selection Notes
Select this component when a single-channel low-side driver with 12 A peak current is required. The inverting configuration dictates input signal polarity relative to the output. Consider the 8-SOIC package constraints for PCB layout. Verify that the 4.5 V to 18 V supply range aligns with the target application's power rails.
Part Context
This part belongs to the MIC4451 series of high-current MOSFET drivers. It is distinct from the non-inverting MIC4452 variant, which shares similar electrical specifications but differs in logic configuration. Both devices utilize the same 8-SOIC footprint and offer comparable speed and current capabilities for low-side driving tasks.
Replacement Considerations
The MIC4452YM serves as a functional substitute if the non-inverting configuration is acceptable. Verify pinout compatibility and ensure the logic inversion difference does not impact circuit timing or control signals.
