MCP1404-E/P

Overview

The MCP1404-E/P is a dual high-speed power MOSFET driver from Microchip Technology, housed in an 8-pin PDIP package. It operates within a supply voltage range of 4.5V to 18V and delivers a typical peak output current of 4.5A per channel. The device features independent enable functions for each driver and provides TTL/CMOS compatible inputs with 300mV hysteresis. It supports low shoot-through currents and offers short delay times of 40ns (typical). The component is rated for operation between -40°C and +125°C.

Feature Summary

• Dual output buffers providing independent control for two MOSFETs
• High capacitive load drive capability with fast rise and fall times
• TTL/CMOS compatible logic inputs with noise immunity via hysteresis
• Latch-up protection against reverse current conditions

Applications

• Automotive industry applications requiring robust gate driving
• Power conversion systems utilizing power MOSFETs
• Industrial motor control circuits
• High-speed switching power supplies

Procurement Notes

Verify the specific suffix 'E/P' confirms the PDIP-8 package and industrial temperature grade (-40°C to +125°C) as distinct from other variants like 'MF'. Ensure compatibility with system voltage requirements of 4.5V to 18V. Confirm RoHS compliance status through official Microchip documentation prior to integration into production designs.

Selection Notes

Select this component when dual-channel isolation and high peak current drive are required for power MOSFETs. The 4.5A output current suits moderate-to-high capacitance loads. Consider the PDIP package for prototyping or through-hole manufacturing needs. Verify input signal levels match TTL/CMOS standards to leverage the built-in hysteresis for noise immunity in electrically noisy environments.

Part Context

The MCP1404 belongs to the MCP1403/4/5 family of dual output buffers and MOSFET drivers. These devices share similar functional architectures but may differ in specific electrical characteristics or packaging options. The MCP1404 specifically emphasizes high-speed performance with low output impedance and short propagation delays, making it suitable for demanding switching applications compared to standard logic buffers.

Replacement Considerations

Check for direct pin-compatible alternatives within the MCP1403/5 series if package availability is constrained. Verify that substitute components maintain the 4.5A peak current rating and 4.5V-18V operating range. Ensure any replacement also supports the required -40°C to +125°C temperature range and TTL/CMOS input compatibility.
