MCP14A0304-E/SN

Overview

The MCP14A0304-E/SN is a dual low-side MOSFET gate driver manufactured by Microchip Technology. It features a non-inverting configuration with a typical peak output current of 3A and operates within a supply voltage range of 4.5V to 18V. The device utilizes CMOS logic and is housed in an 8-SOIC surface-mount package. Key electrical characteristics include rise and fall times of 12ns, a maximum propagation delay of 26ns, and a quiescent supply current of 620uA. It is designed for high-speed switching applications requiring matched performance between its two independent drivers.

Feature Summary

• Dual-channel architecture providing matched high-speed switching capabilities for low-side MOSFETs
• Non-inverting logic configuration simplifies control interface design
• Optimized for minimizing shoot-through currents during commutation events

Applications

• Motor drive systems requiring precise low-side switching
• Power conversion circuits utilizing synchronous rectification
• Industrial automation equipment with high-frequency power stages

Procurement Notes

Verify the specific suffix 'SN' corresponds to the SOIC-8 package variant when sourcing. Confirm that the 'E' designation indicates automotive-grade qualification if required for your application environment. Ensure compatibility with your PCB footprint for the 8-pin small outline integrated circuit format before finalizing procurement orders.

Selection Notes

Select this component when dual isolated low-side driving is necessary with matched timing characteristics. It is suitable for applications where non-inverting logic is preferred over inverting configurations. Consider the 3A peak current capability against the target MOSFET gate charge requirements to ensure adequate drive strength without exceeding thermal limits in the SOIC-8 package.

Part Context

This part belongs to the MCP14A series of high-speed MOSFET gate drivers from Microchip Technology. The series focuses on providing robust switching performance for power management applications. The specific model integrates two drivers into a single compact package, offering a space-efficient solution compared to using discrete driver components or separate single-driver ICs for dual-channel designs.

Replacement Considerations

Check for direct pin-compatible alternatives within the same Microchip family that may offer different packaging options such as TDFN-8 (e.g., MCP14A0304-E/MNY) if board space constraints differ. Verify that any substitute maintains the 3A output current and non-inverting logic requirements.
