MCP1402T-E/OT vs 1EDN7116GXTMA1: Gate Driver Comparison
Quick verdict
For low-side, single-channel MOSFET or IGBT driving in cost-sensitive, thermally constrained applications with moderate switching speed, the MCP1402T-E/OT provides a compact, simple solution with adequate drive current and a wider supply voltage range. For high-side driving of fast-switching N-channel MOSFETs or GaN FETs requiring high peak current and minimal switching losses, the 1EDN7116GXTMA1 is the better choice due to its 2A peak current capability, faster switching times, and high-side bootstrap support.

Design trade-offs
The MCP1402T-E/OT’s 500mA peak current capability suffices for driving moderately sized MOSFETs and IGBTs typically found in low-side switching applications. Its wider supply voltage range (4.5V to 18V) provides design flexibility, especially in systems where a 12V rail is standard or slightly higher voltages are encountered. The SOT-23-5 package is small and suits compact designs, but thermal dissipation will be limited compared to larger packages. The 150°C max junction rating is a notable advantage in harsh environments or where cooling is minimal.
Conversely, the 1EDN7116GXTMA1 targets high-side gate driving with independent channel capability and bootstrap voltage support up to 200V, essential for driving high-side N-channel MOSFETs or GaN FETs in half-bridge or synchronous buck topologies. Its 2A peak output current allows significantly faster gate charge and discharge, reducing switching losses and improving efficiency at higher switching frequencies. The typical 3 ns rise/fall times support very fast transitions, but also impose tighter layout constraints to avoid ringing and EMI. The exposed pad 10-VFDFN package improves thermal performance but increases PCB footprint.
From a layout perspective, the MCP1402T-E/OT’s simpler low-side drive configuration and slower edge rates make it less sensitive to parasitic inductances and PCB layout, easing design in cost-driven applications. The 1EDN7116GXTMA1, with its high current and fast switching, demands careful gate loop minimization, proper decoupling, and optimized PCB stack-up to mitigate EMI and voltage overshoot.
Thermally, the MCP1402T-E/OT’s lower drive current reduces internal power dissipation, suitable for designs without active cooling. In contrast, the 1EDN7116GXTMA1’s higher current capability and faster switching may require more robust thermal management, especially at high switching frequencies or continuous high-load operation.
Cost-wise, the MCP1402T-E/OT is generally lower cost per unit and simpler to implement, while the 1EDN7116GXTMA1’s advanced features and package size increase BOM cost and design complexity. Firmware or control logic differences are minimal as both are non-inverting inputs, but the MCP1402T-E/OT’s defined logic thresholds simplify interfacing with standard 3.3V or 5V logic.
Use-case fit
Choose MCP1402T-E/OT when…
- Driving low-side N- or P-channel MOSFETs or IGBTs in DC-DC converters or motor drivers where peak gate drive current under 500mA is sufficient.
- Operating in environments with elevated ambient temperatures requiring junction ratings up to 150°C.
- The power supply rail can extend up to 18V, and flexibility in supply voltage is required.
- PCB space is constrained and a small SOT-23-5 package is preferred.
- Cost sensitivity and design simplicity outweigh the need for ultra-fast switching or high peak current capability.
Choose 1EDN7116GXTMA1 when…
- Implementing high-side gate drive for N-channel MOSFETs or GaN FETs in synchronous buck, half-bridge, or similar topologies requiring bootstrap voltages up to 200V.
- High switching frequency operation demands fast 3 ns rise/fall times and high peak drive current (2A) to minimize switching losses.
- Thermal management is addressed with exposed pad packages and PCB layouts optimized for heat dissipation.
- The system supply voltage is within 4.2V to 11V and high-side drive capability is mandatory.
- The design requires independent channel control with fast, non-inverting inputs and optimized gate drive for GaN devices.
Drop-in compatibility
The MCP1402T-E/OT and 1EDN7116GXTMA1 are not pin- or footprint-compatible. The MCP1402T-E/OT is housed in a 5-pin SOT-23-5 (SC-74A) package, while the 1EDN7116GXTMA1 uses a 10-pin PG-VSON-10-4 (10-VFDFN) package with an exposed pad for thermal dissipation. Their driven configurations differ fundamentally (low-side vs. high-side), and the 1EDN7116GXTMA1 supports bootstrap voltages and higher supply current. Substituting one for the other would require redesigning the PCB footprint, power supply rails, and possibly the control scheme. Logic input thresholds and drive capabilities differ enough that direct replacement is not feasible without circuit changes.
