MCP14A0454T-E/MNY

Overview

The MCP14A0454T-E/MNY is a high-speed dual low-side MOSFET gate driver from Microchip Technology, housed in an 8-lead TDFN package. It delivers a typical peak output current of 4.5 A with non-inverting logic configuration. The device operates within a supply voltage range of 4.5 V to 18 V and features a typical quiescent supply current of 620 µA. Propagation delays are specified at 16 ns for tD1 and 19 ns for tD2, while rise and fall times are typically 14 ns each. It supports a maximum operating temperature of +125 °C and includes latch-up protection capable of withstanding 500 mA reverse current.

Feature Summary

• Dual non-inverting outputs provide matched high-speed switching characteristics for synchronized control applications.
• Low shoot-through current design minimizes cross-conduction losses during switching transitions.
• Integrated enable feature with hysteresis ensures reliable operation under low-voltage threshold conditions.
• Robust latch-up protection withstands significant reverse current events without damage.

Applications

• High-frequency DC-DC converter topologies requiring precise low-side switching
• Motor drive circuits utilizing dual MOSFET configurations
• Industrial power management systems demanding high capacitive load drive capability

Procurement Notes

Verify the specific suffix MNY corresponds to the 8-lead TDFN (2x3) package when sourcing. Confirm AEC-Q100 qualification requirements if automotive compliance is mandatory. Ensure the ordering part number matches the exact tape-and-reel quantity specifications provided by the manufacturer. Cross-reference datasheet revision dates to confirm parameter consistency.

Selection Notes

Select this component for applications requiring matched dual low-side driving with minimal propagation delay variance. The wide input supply range accommodates various logic levels without external level shifting. Consider the exposed pad thermal performance for high-power density designs. Verify that the 4.5 A peak current meets the gate charge requirements of the target MOSFETs.

Part Context

This device belongs to the MCP14A0453/4/5 family of dual MOSFET drivers. The family shares core electrical characteristics but differs in pinout configurations and package options such as MSOP or SOIC. The MCP14A0454 variant specifically denotes the non-inverting logic configuration within this series.

Replacement Considerations

Direct substitutes include other MCP14A0454 variants with different packages, such as MCP14A0454T-E/MSVAO (MSOP-8). Verify pin compatibility and thermal dissipation capabilities before substituting across package types.
