MCP1403-E/P

Overview

The MCP1403-E/P is a dual low-side gate driver manufactured by Microchip Technology, designed for automotive applications under the AEC-Q100 standard. It features two independent channels capable of sourcing and sinking 4.5A peak current to drive power MOSFETs efficiently. The device operates within a supply voltage range of 4.5V to 18V and supports an inverting logic configuration. Packaged in an 8-pin PDIP format, it provides robust performance with short propagation delays and high noise immunity, making it suitable for demanding power conversion environments.

Feature Summary

• Dual channel architecture providing independent control for two low-side MOSFETs
• High peak output current capability of 4.5A for rapid switching transitions
• Automotive grade qualification ensuring reliability in harsh operating conditions
• Inverting logic input configuration for straightforward interface with control signals

Applications

• Automotive power management systems requiring AEC-Q100 compliance
• DC-DC converter circuits utilizing low-side MOSFET switching
• Motor control applications driving power switches
• Industrial power supplies needing high-speed gate driving

Procurement Notes

Verify the specific suffix 'P' indicates the 8-pin PDIP package when ordering. Confirm that the '-E' designation aligns with the required temperature range and automotive qualification standards for your specific application environment. Ensure compatibility with the 4.5V to 18V supply voltage requirements of your system design before procurement.

Selection Notes

Select this component when dual low-side driving is required with high current capacity. It is appropriate for designs needing automotive reliability certification. Consider the PDIP package constraints if surface mount space is limited. Evaluate the inverting logic requirement against your controller's output polarity to ensure correct signal interfacing without additional inversion circuitry.

Part Context

This part belongs to the MCP1403 family of dual high-speed power MOSFET drivers from Microchip Technology. While other variants exist in SOIC or MF packages, the MCP1403-E/P specifically denotes the through-hole PDIP version. The family is characterized by its ability to drive both N-channel and P-channel MOSFETs efficiently in low-side configurations.

Replacement Considerations

Direct substitutes include other MCP1403 variants such as MCP1403-E/SO or MCP1403-E/MF, provided the package type change is acceptable for the PCB layout. Verify that any replacement maintains the 4.5A output current and AEC-Q100 automotive qualification if those specifications are critical to the design.
