Overview
The MIC4421AYM-TR is a high-speed, low-side MOSFET gate driver manufactured by Microchip Technology. It features an inverting logic configuration and delivers a peak output current of 9A. The device operates within a supply voltage range of 4.5V to 18V. It utilizes an 8-SOIC surface-mount package with a tape-and-reel quantity of 2500 units. Typical rise and fall times are 20ns and 24ns, respectively. The operational temperature range extends from -40°C to +85°C.
Feature Summary
- Provides rugged 9A peak output capability for driving large MOSFETs
- Features fast switching speeds with 20ns rise and 24ns fall times
- Accepts standard logic inputs directly without external level shifting
Applications
- High-speed power switching circuits
- Motor control systems
- DC-DC converter designs
Procurement Notes
Verify the specific suffix 'AYM-TR' confirms the SOIC-8 surface mount package and tape-and-reel packaging format. Ensure the inverting configuration aligns with the system design requirements. Confirm the operating temperature range meets the application environment specifications before finalizing procurement.
Selection Notes
Select this component when a single-channel, low-side driver with high peak current is required. The inverting input type must be considered for logic interface compatibility. Compare against non-inverting variants like the MIC4422 series if signal phase inversion is not desired. Ensure the 8-SOIC footprint fits the PCB layout constraints.
Part Context
This part belongs to the MIC4421A/MIC4422A family of bipolar/CMOS/DMOS process drivers. It serves as the inverting counterpart to the MIC4422A. The family is designed for efficient and easy-to-use MOSFET gate driving applications requiring robust performance and improved safe operating margins.
Replacement Considerations
The MIC4421AZM and MIC4421AXM are catalog parts within the same family. Verify pinout and electrical specifications match before substitution. The MIC4422AYM-TR offers identical electrical performance but with non-inverting logic.
