MCP1403T-E/SN

Overview

The MCP1403T-E/SN is a dual high-speed low-side MOSFET gate driver manufactured by Microchip Technology. It provides matched output characteristics with a peak drive current of 4.5 A per channel. The device operates within a supply voltage range of 4.5 V to 18 V and features an inverting logic configuration. Key electrical parameters include rise and fall times of 12 ns, ensuring rapid switching performance. It is housed in an 8-pin SOIC surface-mount package.

Feature Summary

• Dual independent low-side gate drivers with matched propagation delays for synchronized switching
• High peak output current capability of 4.5 A to minimize switching losses
• Inverting logic interface compatible with standard digital control signals
• Compact 8-lead SOIC surface-mount packaging for space-constrained designs

Applications

• Motor control systems requiring precise dual-MOSFET timing
• DC-DC converter topologies utilizing half-bridge or full-bridge configurations
• Industrial power supplies needing fast-switching low-side drive
• Automotive electronics applications demanding robust gate driving

Procurement Notes

Verify the specific suffix 'SN' corresponds to the 8-lead SOIC package variant when ordering. Confirm that the 'T' designation indicates tape-and-reel packaging if reel quantity is required. Ensure compatibility with the 4.5 V to 18 V operating voltage range for your target application. Cross-reference the datasheet revision date to confirm pinout consistency with existing board layouts.

Selection Notes

Select this component when dual low-side driving with matched delay is critical. The 4.5 A drive strength suits medium-power MOSFETs. Consider thermal dissipation requirements given the SOIC package limitations. Verify input logic levels align with the controller's output voltage. This part is suitable for applications where cost-effective dual-channel isolation is needed without integrated high-side drivers.

Part Context

This device belongs to the MCP1403 family of dual MOSFET gate drivers from Microchip. It shares functional similarities with the MCP1402 but offers higher drive current. The T-E/SN designation specifies the industrial temperature range, tape-and-reel packaging, and SOIC footprint. It serves as a direct replacement for legacy dual low-side drivers in motor and power conversion circuits.

Replacement Considerations

• MCP1403-E/SN (Same function, different packaging format)
• MCP1403T-E/SO (Alternative SOIC variant)
