MCP1404T-E/SN

Overview

The MCP1404T-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 within a supply voltage range of 4.5V to 18V and supports CMOS and TTL logic inputs. Key electrical parameters include rise and fall times of 28ns, with a quiescent supply current of 2mA. It is housed in an 8-lead SOIC package (surface mount) and is rated for operation from -40°C to +125°C.

Feature Summary

• Dual independent low-side gate drivers for synchronous rectification or half-bridge applications
• High peak output current capability of 4.5A for fast switching transitions
• Compatible with standard CMOS and TTL logic input levels
• Automotive qualification compliant with AEC-Q100 standards

Applications

• Synchronous buck and boost DC-DC converters
• Motor control systems requiring low-side switching
• Industrial power supply inverters
• Automotive electronics modules

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging versus 'E/MF' tube variants. Confirm the 'SN' suffix corresponds to the SOIC-8 package dimensions. Ensure the order quantity aligns with the standard reel size of 3,300 units if bulk procurement is required. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.

Selection Notes

Select this component when dual low-side driving with 4.5A peak current is required. Consider the 28ns propagation delay for high-frequency applications. Evaluate thermal performance given the SOIC-8 package constraints. Compare against higher current alternatives like the MCP14A series if load requirements exceed 4.5A. Verify logic level compatibility with the controlling microcontroller.

Part Context

This part belongs to the MCP14xx family of MOSFET gate drivers from Microchip Technology. It complements other variants such as the MCP1407 (high-side) and MCP14A series (higher current). The family focuses on providing robust, high-speed switching capabilities for power management ICs and discrete MOSFET applications in industrial and automotive sectors.

Replacement Considerations

Direct pin-to-pin replacements may include the MCP1404-E/SN (tube version) or MCP1404T-E/MF (DFN package, verify footprint). For higher current needs, consider the MCP14A0304T-E/SN. Always validate electrical parameters and package dimensions before substitution.
