MCP1406-E/AT

Overview

The MCP1406-E/AT is a low-side gate driver IC from Microchip Technology, housed in a TO-220-5 package. It features a single output with a peak drive current capability of 6A. The device operates within an input supply voltage range of 4.5V to 18V and supports high capacitive load drive, handling 2500 pF in 20 ns and 6800 pF in 40 ns. Typical propagation delay is 40 ns, with matched rise and fall times. It includes latch-up protection capable of withstanding 1.5A reverse current and logic inputs that tolerate negative swings up to 5V.

Feature Summary

• High peak output current capability for efficient power MOSFET switching
• Low shoot-through and cross-conduction current in the output stage
• Latch-up protected design ensuring robustness against reverse current events

Applications

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

Procurement Notes

Verify the specific suffix AT corresponds to the TO-220-5 package configuration as documented in official Microchip datasheets. Confirm the -E designation indicates the extended temperature rating appropriate for your operational environment. Ensure compatibility with existing PCB footprints for the TO-220-5 form factor before finalizing procurement orders.

Selection Notes

Select this component when a single-channel, non-inverting low-side driver with high peak current is required. It serves as a pin-compatible replacement for older TC4420 devices. Consider its wide operating voltage range and fast switching speeds for applications demanding precise timing and high efficiency in power management systems.

Part Context

This part belongs to the MCP1406/07 family of buffers and MOSFET drivers. These devices are improved versions of the TC4420/TC4429 series, offering enhanced performance characteristics such as lower supply current and better matching of rise/fall times while maintaining pin compatibility with legacy components.

Replacement Considerations

The MCP1406-E/MF is a pin-compatible alternative available in an SOIC package. Verify package dimensions and thermal requirements when substituting between TO-220-5 and surface-mount options.
