MCP1407-E/AT

Overview

The MCP1407-E/AT is a single-output MOSFET gate driver IC from Microchip Technology, housed in a TO-220-5 through-hole package. It provides a peak output current of 6A for both sourcing and sinking. The device operates with a supply voltage range of 4.5V to 18V and supports CMOS and TTL logic inputs. Typical rise and fall times are 20ns, with a maximum turn-on delay time of 50ns. It functions as a non-inverting low-side driver suitable for IGBT and N-channel/P-channel MOSFET applications.

Feature Summary

• Provides high peak drive current capability for rapid switching
• Features low shoot-through current to minimize power loss
• Supports direct interface with standard CMOS and TTL logic levels

Applications

• Low-side MOSFET driving in power conversion circuits
• IGBT gate control in motor drives
• Isolated power supply transformer drivers

Procurement Notes

Verify the specific suffix AT indicates the TO-220-5 package configuration. Confirm the -E temperature grade matches the required operating range of -40°C to +150°C TJ. Ensure the non-inverting logic input aligns with the system control signals. Check RoHS compliance status if restricted substances are mandated by the end application.

Selection Notes

Select this component when a robust single-channel driver with 6A peak current is required for low-side switching. The TO-220-5 package offers thermal advantages for higher power dissipation compared to surface-mount options. Consider the 4.5V minimum supply voltage constraint against the available system rails. The non-inverting configuration simplifies logic interfacing without additional inversion stages.

Part Context

This part belongs to the MCP1406/07 family of buffers and MOSFET drivers. The MCP1407 variant specifically offers the 6A peak current capability, whereas other family members may differ in drive strength or configuration. The AT suffix denotes the specific TO-220-5 through-hole packaging format used for this industrial-grade version.
