MCP14A0451T-E/MS

Overview

The MCP14A0451T-E/MS is a single-channel MOSFET gate driver manufactured by Microchip Technology. It provides a peak output current of 4.5 A and operates within a supply voltage range of 4.5 V to 18 V. The device features an inverting logic configuration with a low input threshold, facilitating direct interface with various logic families. Key timing parameters include a rise time of 12 ns and a fall time of 12 ns. It is housed in an 8-pin MSOP surface-mount package and supports operation temperatures from -40°C to +125°C.

Feature Summary

• Delivers high-speed switching performance with 4.5 A source/sink capability for efficient MOSFET control.
• Incorporates a low input threshold design to ensure reliable triggering from standard logic outputs.
• Includes an integrated enable pin for precise power management and channel control.

Applications

• Low-side switching in DC-DC converter topologies
• Motor drive circuits requiring fast MOSFET turn-on/off
• Industrial power supply gate driving

Procurement Notes

Verify the specific suffix 'E/MS' confirms the MSOP-8 package and tape-and-reel packing media. Confirm RoHS compliance status as indicated in official documentation. Ensure the inverting configuration aligns with system logic requirements before procurement.

Selection Notes

Select this component when a single-channel, high-current (4.5 A) solution is required for low-side applications. The inverting output necessitates checking signal polarity against the control source. The MSOP-8 package offers a compact footprint suitable for space-constrained designs compared to larger packages.

Part Context

This part belongs to the MCP14A0xxx series of high-speed MOSFET drivers from Microchip. The series differentiates models primarily by output current capacity (e.g., 0.5A, 1.5A, 3.0A, 4.5A) and channel count. The MCP14A0451 specifically denotes the 4.5 A single-channel variant with inverting logic.

Replacement Considerations

Direct substitutes include other MCP14A045x variants if non-inverting logic or different packaging is acceptable. Cross-reference with MCP14A0452T-E/MS for non-inverting functionality in the same package. Verify thermal and electrical compatibility with any alternative single-channel 4.5 A drivers.
