Overview
The MIC4420BM-TR is a low-side MOSFET gate driver manufactured by Microchip Technology. It features a single non-inverting output capable of delivering a peak current of 6A. The device operates within a supply voltage range of 4.5V to 18V and utilizes an 8-SOIC surface-mount package. Key electrical characteristics include matched rise and fall times of 25ns, a typical propagation delay of 55ns, and an output impedance of approximately 2.5Ω. It supports logic inputs from 2.4V up to the supply voltage.
Feature Summary
- Non-inverting low-side configuration for driving power MOSFETs
- High peak output current capability of 6A
- Input protection against negative voltage swings up to 5V
- Latch-up protected design with high reverse output current tolerance
Applications
- Switch mode power supplies
- Motor control systems
- Pulse transformer drivers
- Class-D switching amplifiers
Procurement Notes
Verify the specific suffix 'BM' against the official datasheet to confirm temperature grade and packaging specifications. Ensure the ordering information matches the required tape and reel quantity. Cross-reference the manufacturer part number with the latest revision history to confirm component availability and compliance status before finalizing procurement.
Selection Notes
Select this component when a non-inverting low-side driver with 6A peak current is required. It is suitable for applications needing fast switching speeds with matched rise and fall times. Consider the 8-SOIC package constraints and the 4.5V to 18V supply range. Verify that the input logic levels are compatible with the 2.4V minimum threshold.
Part Context
The MIC4420 is part of the MIC4420/4429/429 family of MOSFET drivers designed for robust performance in demanding electrical environments. These drivers utilize a BiCMOS/DMOS process to provide rail-to-rail voltage swings and low power dissipation. The family is pin-compatible with other variants, offering flexibility in design implementation for various power management applications.
Replacement Considerations
MIC4420YM-TR: Same series, different package (MSOP). MIC4420YN: Same series, different package (PDIP). MIC4429BM-TR: Inverting version of the same driver.
