MCP1403-E/SN

Overview

The MCP1403-E/SN is a dual high-speed power MOSFET gate driver manufactured by Microchip Technology. It features two independent low-side drivers capable of sourcing and sinking 4.5A peak output current. The device operates with a supply voltage range from 4.5V to 18V. It utilizes an 8-pin SOIC surface-mount package. Key electrical parameters include a maximum propagation delay of 28ns and an operating junction temperature range of -40°C to +150°C.

Feature Summary

• Dual independent channel configuration for driving two external MOSFETs
• High peak output current capability of 4.5A for fast switching
• Low on-resistance output stage to minimize conduction losses
• Wide supply voltage range supporting various logic levels

Applications

• DC-DC converter synchronous rectification
• Motor control bridge drivers
• Power supply gate drive circuits

Procurement Notes

Verify the suffix 'SN' confirms the 8-pin SOIC package and industrial temperature grade. Ensure the datasheet revision matches the required specifications. Confirm RoHS compliance status if mandated by project requirements. Check for any specific ordering suffix variations that may affect pinout or thermal performance.

Selection Notes

Select this component when dual low-side driving is required with high current capability. The 4.5A output suits medium-power applications. Consider the 28ns propagation delay for switching frequency limits. The wide operating temperature range supports harsh environments. Verify input logic compatibility with the host controller voltage levels.
