Product details

6A peak drive in a compact SOIC

The MCP1406-E/SN is a single-channel low-side gate driver from Microchip, delivering 6A peak source and sink current from a 4.5V to 18V supply rail. It drives IGBTs, N-channel, and P-channel MOSFETs with a 20 ns typical rise and fall time, making it a fit for fast-switching power stages in DC-DC converters, motor drives, and class-D amplifiers. The inverting input logic thresholds of 0.8V (VIL) and 2.4V (VIH) allow direct interface with 3.3V or 5V PWM controllers without external level translation. The single driver channel is suited for low-side switch topologies where one gate signal controls the main power FET or IGBT.

The 6A peak output current is specified for both source and sink, meaning the driver can charge and discharge the gate capacitance symmetrically. With 20 ns typical rise/fall times, switching losses in the external FET are minimised at moderate frequencies — a 1 nF gate load transitions in roughly 20 ns, supporting switching frequencies into the hundreds of kilohertz.

Frequently asked questions

How does MCP1406-E/SN compare to TC4424EPA as a second-source?

The TC4424EPA is a dual-channel non-inverting low-side driver with 3A peak output in a through-hole PDIP-8 package. The MCP1406-E/SN is a single-channel inverting driver with 6A output in an 8-SOIC surface-mount package. They are not pin-compatible — a board layout change is required to swap between them — but both drive MOSFET/IGBT gates in low-side configurations.

What compliance documentation does Microchip provide for MCP1406-E/SN?

The MCP1406-E/SN is ROHS3 compliant. Microchip typically provides a certificate of compliance and material declaration upon request through the supply chain.

Where can I buy MCP1406-E/SN and check lead time?

The MCP1406-E/SN is sourced to order through independent distribution.
