MCP14A0303-E/MNY

Overview

The MCP14A0303-E/MNY is a dual MOSFET gate driver from Microchip Technology, housed in an 8-pin TDFN package. It provides two inverting outputs with a peak output current of 3 A. The device operates within a supply voltage range of 4.5 V to 18 V and supports CMOS logic inputs. Key timing parameters include a maximum propagation delay of 26 ns, rise time of 12 ns, and fall time of 12 ns. Internal source/sink resistance is specified at 5 Ohms. It functions across an industrial temperature range of -40°C to +125°C with a quiescent current of 620 uA and power dissipation up to 1.85 W.

Feature Summary

• Dual-channel configuration providing independent high-side and low-side drive capabilities
• Inverting logic interface compatible with standard CMOS control signals
• Automotive-grade qualification ensuring reliability under harsh environmental conditions

Applications

• Industrial motor control systems requiring precise switching
• Power conversion circuits utilizing matched high-speed MOSFETs
• Automotive electronics compliant with AEC-Q100 standards

Procurement Notes

Verify the specific suffix MNY corresponds to the TDFN-8 tube packaging format before ordering. Confirm that the inverting configuration aligns with the system's logical requirements for the intended application. Ensure thermal management strategies account for the specified power dissipation limits during operation.

Selection Notes

Select this component when dual isolated or complementary gate driving is required with matched timing characteristics. The inverting topology suits applications where signal inversion is necessary for bridge configurations. Consider the 3 A drive capability for medium-power MOSFETs and verify input threshold compatibility with the controlling microcontroller.

Part Context

This part belongs to the MCP14A03xx series of high-speed MOSFET drivers designed for robust performance. The E suffix indicates automotive grade qualification, while MNY denotes the specific tape-and-reel or tube packaging variant. It complements non-inverting counterparts like the MCP14A0302 series for complete half-bridge solutions.

Replacement Considerations

Direct substitutes within the same family include other variants of the MCP14A03xx series with matching pinouts and electrical specifications. Verify package compatibility and logic direction (inverting vs. non-inverting) when cross-referencing with similar dual-driver ICs from Microchip or other manufacturers.
