MCP14A0303T-E/MS

Overview

The MCP14A0303T-E/MS is a dual, high-speed, low-side inverting MOSFET gate driver manufactured by Microchip Technology. It features matched propagation delays for precise timing control in bridge configurations. The device operates with a supply voltage range of 4.5 V to 18 V and delivers a peak output current of 3 A. Key electrical parameters include a rise time of 12 ns and a fall time of 12 ns. It is housed in an 8-lead MSOP package and supports surface mount installation.

Feature Summary

• Dual channel configuration with matched propagation delays for synchronized switching
• High-speed operation with 12 ns rise and fall times
• Inverting logic configuration for low-side drive applications
• Robust 3 A peak output current capability

Applications

• Low-side MOSFET driving in DC-DC converters
• Synchronous rectification circuits
• Motor control bridge drivers
• Power supply gate drive stages

Procurement Notes

Verify the specific suffix 'E/MS' confirms the MSOP-8 package and industrial temperature grade. Ensure compatibility with the target PCB footprint for the 8-lead small outline package. Confirm that the inverting logic aligns with the control signal polarity requirements of the system design before finalizing procurement.

Selection Notes

Select this component when matched delay characteristics are critical for minimizing shoot-through in half-bridge topologies. The 3 A drive strength suits medium-power MOSFETs. Consider the inverting configuration requirement; if non-inverting signals are needed, alternative part numbers within the MCP14A series must be evaluated. Verify voltage levels match the 4.5 V to 18 V operating range.

Part Context

This device belongs to the MCP14A series of high-speed MOSFET gate drivers from Microchip Technology. The series offers various configurations including single and dual channels with both inverting and non-inverting options. The MCP14A0303T-E/MS specifically addresses applications requiring dual low-side drive with precise timing matching.

Replacement Considerations

Direct substitutes within the same family include MCP14A0302T-E/MS (non-inverting) or MCP14A0304T-E/MSVAO (dual non-inverting). Cross-package replacements such as SOIC-8 variants may require schematic review due to pinout differences.
