MCP1404-E/SN

Overview

The MCP1404-E/SN is a dual high-speed power MOSFET driver manufactured by Microchip Technology. It features two independent non-inverting drivers with a typical peak output current of 4.5A. The device operates within a supply voltage range of 4.5V to 18V and utilizes an 8-pin SOIC package. Key electrical characteristics include a typical rise time of 12ns, fall time of 12ns, and propagation delay of 40ns. It provides TTL/CMOS compatible inputs with 300mV hysteresis for noise immunity.

Feature Summary

• Dual independent driver configuration with separate enable functions
• High capacitive load drive capability for rapid gate charging
• Low shoot-through current in the output stage to minimize cross-conduction losses
• TTL/CMOS compatible logic inputs with built-in hysteresis

Applications

• Power MOSFET switching control in motor drives
• DC-DC converter gate driving applications
• Inverter circuits requiring isolated or buffered control signals
• Industrial power management systems

Procurement Notes

Verify the specific suffix 'E/SN' corresponds to the industrial temperature range (-40°C to +125°C) and SOIC-8 package when sourcing. Confirm RoHS compliance status through official Microchip documentation. Ensure the ordering part number matches the exact pinout and electrical specifications required for your design to avoid compatibility issues with existing PCB footprints.

Selection Notes

Select this component when dual-channel MOSFET driving is required with high peak current capabilities up to 4.5A. It is suitable for applications needing fast switching speeds with low propagation delay. Consider the 4.5V to 18V operating range for compatibility with various logic levels. The non-inverting configuration simplifies control logic integration compared to complementary pairs.

Part Context

This device belongs to the MCP1403/4/5 family of dual output buffers and MOSFET drivers from Microchip Technology. These components are designed to provide robust gate drive signals for power switches. The MCP1404 specifically offers 4.5A peak current, distinguishing it from lower-current variants in the same series while maintaining similar interface characteristics and packaging options.

Replacement Considerations

Compatible substitutes within the same family include MCP1403 and MCP1405, which share similar pinouts but may differ in peak output current ratings. Verify that any replacement maintains the required 4.5A to 18V supply range and SOIC-8 package dimensions to ensure direct board compatibility without redesign.
