Overview
The MIC4421ABM-TR is a single-channel low-side MOSFET gate driver manufactured by Microchip Technology. It features a non-inverting input configuration and delivers a peak output current of 9A for both sourcing and sinking operations. The device operates within a supply voltage range of 4.5V to 18V and supports logic levels with VIL of 0.8V and VIH of 3V. Typical rise and fall times are 15ns and 20ns, respectively. It is housed in an 8-SOIC package (0.154" width) and is rated for an operating junction temperature range of -55°C to 150°C.
Feature Summary
- Provides high-current 9A peak drive capability for efficient switching of N-channel power MOSFETs.
- Features fast propagation delays with typical rise and fall times to minimize switching losses.
- Operates over an extended industrial temperature range suitable for harsh environments.
Applications
- Low-side switching control for power MOSFETs in motor drive circuits
- Gate driving for power stages in DC-DC converters
- High-speed switching applications requiring robust current drive
Procurement Notes
Verify component authenticity through authorized Microchip distributors or direct channels. Confirm the specific suffix matches the required package and tape/reel specifications. Check for RoHS compliance status as indicated in official documentation. Ensure storage conditions meet moisture sensitivity level requirements prior to assembly.
Selection Notes
Select this component when a single low-side driver with high peak current is required. Compare against the MIC4422 series if an inverting input configuration is needed instead. Verify that the 8-SOIC package dimensions fit the target PCB layout constraints. Ensure the supply voltage remains within the 4.5V to 18V operational window.
Part Context
This part belongs to the MIC4421/4422 family of high-speed MOSFET drivers. These devices utilize a Bipolar/CMOS/DMOS process to achieve high performance. The MIC4421 variant specifically provides a non-inverting output, distinguishing it from the inverting MIC4422 model within the same product line.
Replacement Considerations
The MIC4422ABM-TR serves as a functional substitute if an inverting input configuration is acceptable. Other compatible alternatives include the MIC4421YM-TR for different packaging options. Verify pin compatibility and electrical parameters before substitution.
