MCP1405-E/P

Overview

The MCP1405-E/P is a low-side gate driver IC manufactured by Microchip Technology. It features dual outputs capable of sourcing and sinking 4.5 A each, designed for driving power MOSFETs. The device supports both inverting and non-inverting logic inputs. It operates within a supply voltage range of 4.5 V to 18 V. The component is qualified under the AEC-Q100 standard for automotive applications. It is housed in an 8-pin PDIP package and functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

• Dual high-current output drivers providing 4.5 A source and sink capability
• Automotive qualification compliant with AEC-Q100 standards
• Supports both inverting and non-inverting input configurations
• Operates over an extended industrial and automotive temperature range

Applications

• Power management systems in automotive electronics
• Motor control circuits requiring robust MOSFET switching
• Industrial power conversion and inverters

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm package type and temperature grade. Ensure the ordering code matches the required PDIP configuration. Confirm AEC-Q100 compliance requirements align with your system specifications before procurement.

Selection Notes

Select this component when dual low-side drive with high peak current is required. The PDIP package suits through-hole assembly processes. Verify that the input logic levels are compatible with the controlling microcontroller or DSP. Consider thermal dissipation requirements for the PCB layout given the 4.5 A output capability.

Part Context

This part belongs to the MCP1405 series of dual high-speed power MOSFET drivers from Microchip Technology. The series includes variants with different packages such as SOIC and SSOP. The 'E' designation typically indicates the extended temperature grade, while '/P' specifies the PDIP package style within the product line.

Replacement Considerations

Check for direct pin-compatible alternatives within the same family, such as other MCP1405 variants with different packaging. Verify that any substitute maintains the 4.5 A current rating and AEC-Q100 qualification if automotive use is intended.
