MCP1404-E/MF

Overview

The MCP1404-E/MF is a dual high-speed power MOSFET driver from Microchip Technology, housed in an 8-pin DFN-S package. It operates within a supply voltage range of 4.5V to 18V and supports an extended temperature range of -40°C to +125°C. The device provides a typical peak output current of 4.5A with low output impedance of 2.2 ohms. It features independent enable functions for each driver and offers TTL/CMOS compatible inputs with 300mV hysteresis. Key performance metrics include charging 2200pF gate capacitance in under 28ns (max) and short delay times of 40ns (typ).

Feature Summary

• Dual non-inverting outputs with independent enable control for precise switching management.
• High capacitive load drive capability ensuring rapid MOSFET gate charging.
• Low shoot-through and cross-conduction currents in the output stage for improved efficiency.
• Robust input protection including latch-up resistance and tolerance for negative voltage swings.

Applications

• Power supply circuits requiring fast MOSFET switching.
• Motor control systems utilizing high-side or low-side drivers.
• Industrial automation equipment needing reliable gate drive signals.
• Battery management systems with isolated or non-isolated topologies.

Procurement Notes

Verify the specific suffix 'MF' corresponds to the 8-pin DFN-S package and tube packaging configuration when ordering. Confirm that the '-E' designation aligns with the required industrial temperature range specifications. Ensure compatibility with existing PCB footprints for the DFN-S form factor. Cross-reference the datasheet revision date to confirm latest electrical characteristics. Validate that the supplier provides original manufacturer documentation for quality assurance.

Selection Notes

Select this component when dual-channel isolation and high peak current are required for efficient power stage driving. Consider the 4.5V minimum supply voltage constraint against system logic levels. Evaluate the 2.2-ohm output impedance against target switching speeds and gate charge requirements. Assess the need for independent enable pins versus tied configurations. Compare thermal dissipation capabilities of the DFN-S package against available board space.

Part Context

This part belongs to the MCP1403/4/5 family of 4.5A dual output buffers and MOSFET drivers. It shares core architectural features with siblings like the MCP1403 and MCP1405 but differs in pinout or specific functional variations. The family is designed for applications demanding fast switching times and noise immunity. The MCP1404 specifically targets dual-driver scenarios without additional complexity found in higher-channel devices.

Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source material. Verify pin-to-pin compatibility with alternative dual MOSFET drivers before substitution. Check if competitor parts match the 4.5A peak current and 4.5V-18V supply range. Ensure equivalent hysteresis and propagation delay specifications are met. Confirm package dimensions for mechanical fit if replacing in existing designs.
