MCP1407-E/SN

Overview

The MCP1407-E/SN is a single-channel low-side gate driver from Microchip Technology, housed in an 8-SOIC package. It delivers 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 logic inputs compatible with CMOS and TTL standards, defined by VIL of 0.8V and VIH of 2.4V. Typical rise and fall times are 20ns, with a propagation delay of approximately 40ns. It functions within a temperature range of -40°C to +125°C and holds AEC-Q100 automotive qualification.

Feature Summary

• Provides high peak drive current capability of 6A for efficient switching of power MOSFETs and IGBTs
• Features matched rise and fall times to minimize shoot-through currents in the output stage
• Includes latch-up protection capable of withstanding reverse current conditions
• Accepts logic inputs that withstand negative voltage swings up to 5V

Applications

• Switch mode power supplies
• Motor and solenoid drive circuits
• Pulse transformer drive applications

Procurement Notes

Verify the specific suffix 'SN' confirms the 8-SOIC surface-mount package and tube packaging format. Confirm the '-E' grade indicates the extended industrial temperature range of -40°C to +125°C. Ensure the 'VAO' designation is not required if automotive reliability beyond standard qualification is needed. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.

Selection Notes

Select this component when a single-channel, non-inverting driver with 6A peak current is required. It is suitable for driving capacitive loads up to 2500pF within 20ns. Consider the 8-SOIC package constraints for PCB layout. Verify input logic levels match the control system's 0.8V/2.4V thresholds. Compare against pin-compatible alternatives like the TC4420 if legacy replacement is necessary.

Part Context

This part belongs to the MCP1406/07 family of buffers and MOSFET drivers. It serves as an improved version of the TC4420/TC4429 series, offering enhanced performance characteristics. The family includes complementary inverting (MCP1406) and non-inverting (MCP1407) variants. These devices are designed for general-purpose high-speed switching applications requiring robust drive capabilities.
