MCP1416T-E/OT vs MCP1407T-E/SN: Gate Driver IC Comparison
Quick verdict
For low-side gate driving applications where board space is limited and moderate gate drive current suffices, the MCP1416T-E/OT is the preferable choice due to its compact SOT-23-5 package and adequate 1.5A peak drive current. Conversely, for designs demanding higher transient gate drive capability to switch large MOSFETs or IGBTs faster, the MCP1407T-E/SN offers a clear advantage with its 6A peak source/sink current, albeit at the cost of a larger SOIC-8 footprint and slightly reduced maximum junction temperature.

Design trade-offs
The most significant difference between the MCP1416T-E/OT and MCP1407T-E/SN is their peak output current capability: 1.5A versus 6A. This translates directly into how aggressively you can drive the MOSFET or IGBT gate capacitance. Higher peak current reduces switching times, minimizing transition losses and electromagnetic interference (EMI). For high-current power stages or fast switching frequencies (above a few hundred kHz), the MCP1407T-E/SN can improve overall efficiency by driving gates faster and cleaner.
However, the MCP1407T-E/SN’s larger package (8-SOIC) increases PCB footprint and parasitic inductances compared to the compact SOT-23-5 of the MCP1416T-E/OT. This can complicate high-density layouts or designs with tight space constraints. The smaller MCP1416T-E/OT package also favors lower parasitic capacitances and inductances, which can be beneficial when switching smaller MOSFETs or operating at moderate frequencies.
Thermally, the MCP1416T-E/OT supports junction temperatures up to 150°C, 25°C higher than the MCP1407T-E/SN, making it potentially more robust in harsh environments or under high ambient temperature conditions. That said, the MCP1407T-E/SN’s higher current capability means it can dissipate more power during switching, requiring careful thermal management and possibly a larger copper area for heat sinking.
From a supply standpoint, both devices operate over the same 4.5V to 18V range, accommodating typical gate drive voltages for logic-level and standard MOSFETs alike. Both are non-inverting low-side drivers, simplifying input logic considerations.
Cost at volume typically favors smaller packages; the MCP1416T-E/OT’s SOT-23-5 package is generally less expensive and easier to place with automated pick-and-place equipment than the 8-pin SOIC. However, if switching performance is critical, the MCP1407T-E/SN’s higher drive current can offset cost differences by enabling more efficient power stages.
Use-case fit
Choose MCP1416T-E/OT when…
- Board space is at a premium, and a compact SOT-23-5 footprint is required.
- Switching moderate gate charge MOSFETs or IGBTs at frequencies below ~100 kHz.
- Operating environments demand higher junction temperature capability (up to 150°C).
- Gate drive current of 1.5A peak is sufficient to meet switching speed and EMI requirements.
- Cost sensitivity favors smaller packages and simpler layouts.
Choose MCP1407T-E/SN when…
- Driving large gate charge MOSFETs or IGBTs requiring up to 6A peak drive current.
- High-frequency switching (>100 kHz) demands fast transitions to minimize switching losses.
- EMI reduction is critical, and aggressive gate drive slew rates are beneficial.
- PCB space is available for a larger SOIC-8 footprint.
- Thermal management can accommodate the increased power dissipation from higher drive currents.
Drop-in compatibility
There is no indication that the MCP1416T-E/OT and MCP1407T-E/SN are pin-compatible. The MCP1416T-E/OT uses a 5-pin SOT-23 package (SC-74A footprint), while the MCP1407T-E/SN comes in an 8-pin SOIC package. Their pinouts and package sizes differ substantially, so substitution requires a complete PCB redesign including footprint and routing changes. Signal and power pin assignments are not interchangeable based on the available data.
