MCP1403T-E/SO

Overview

The MCP1403T-E/SO is a dual high-speed power MOSFET driver manufactured by Microchip Technology. It provides independent high-current drive for two N-channel or P-channel MOSFETs, delivering up to 4.5A peak source and sink current. The device operates with a supply voltage range of 4.5V to 18V and features low propagation delay for efficient switching. It includes built-in shoot-through protection to prevent simultaneous conduction in half-bridge configurations. The component is available in a 16-pin SOIC package and is rated for operation from -40°C to +125°C.

Feature Summary

• Dual independent channel architecture supporting high-speed switching applications
• Integrated shoot-through protection mechanism to enhance circuit reliability
• High peak output current capability for rapid MOSFET gate charging

Applications

• Half-bridge and full-bridge power converter topologies
• Motor control systems requiring precise gate drive timing
• DC-DC converter designs utilizing synchronous rectification

Procurement Notes

Verify the specific suffix 'E/SO' confirms the 16-pin SOIC package and industrial temperature grade. Ensure the datasheet revision matches your design requirements. Confirm that the tape and reel quantity aligns with production needs. Cross-reference pinouts with existing PCB layouts to avoid compatibility issues during integration.

Selection Notes

Select this component when dual isolated gate drives are required within a single package. Consider the 4.5A current rating against the total gate charge of the target MOSFETs. Evaluate the propagation delay specifications for high-frequency switching applications. Verify that the operating voltage range covers the system's logic and supply levels.

Part Context

This part belongs to the MCP1403 family of dual MOSFET drivers. It shares functional similarities with other members like the MCP1403-E/MF but differs in packaging. The family is designed for robust performance in industrial and automotive environments. It complements single-channel drivers by providing matched characteristics for bridge circuits.

Replacement Considerations

Potential substitutes include MCP1403-E/SN and MCP1403-E/SO. Verify pinout compatibility before substitution. Check if alternative packages meet thermal and spatial constraints. Ensure equivalent electrical parameters such as peak current and propagation delay.
