Overview
The MIC4451ABM-TR is a low-side MOSFET gate driver manufactured by Microchip Technology. It features a single inverting output capable of delivering a peak current of 12A. The device operates within a supply voltage range of 4.5V to 18V and utilizes an SOIC-8 surface-mount package. Key electrical parameters include rise and fall times of 25ns, with maximum on/off delay times of 80ns. It functions reliably across an operating temperature range of -40°C to +85°C.
Feature Summary
- Provides high peak output current for driving large MOSFETs
- Accepts logic inputs from 2.4V to VS without external components
- Withstands negative input swings up to 5V without damage
- Inherently immune to latch-up due to fully isolated process
Applications
- Power supply circuits requiring efficient MOSFET switching
- Motor control systems utilizing low-side drive configurations
- Industrial automation equipment needing robust gate drivers
Procurement Notes
Verify the specific suffix 'ABM' against official Microchip documentation to confirm exact tape-and-reel packaging and temperature grade specifications. Ensure compatibility with standard SOIC-8 footprints during PCB layout. Confirm RoHS compliance status through the manufacturer's latest datasheet or certification documents before finalizing procurement orders.
Selection Notes
Select this component when a low-side inverting driver with 12A peak capability is required. It is suitable for applications needing wide supply voltage operation between 4.5V and 18V. Consider the 25ns switching speed for moderate-frequency switching applications. Verify that the inverting logic configuration aligns with the system control requirements.
Part Context
This part belongs to the MIC4451/MIC4452 family of CMOS MOSFET drivers designed for tough, efficient, and easy-to-use performance. The MIC4451 variant specifically provides inverting functionality, contrasting with the non-inverting MIC4452. These drivers replace multiple discrete components to reduce PCB area and assembly costs while offering improved safe operating margins for power MOSFETs.
Replacement Considerations
The MIC4452BM-TR serves as the non-inverting counterpart within the same series. For pin-compatible alternatives, verify specific Microchip cross-reference lists for other low-side drivers in the SOIC-8 package.
