MCP1416T-E/OT vs 2EDN7533RXTMA1 Gate Driver ICs: Detailed Comparison
Quick verdict
For simple, low-current low-side MOSFET or IGBT driving in compact, cost-sensitive designs, the MCP1416T-E/OT is a solid choice due to its small SOT-23 footprint and adequate 1.5A drive capability. For higher-performance applications requiring faster switching, higher peak current, and dual independent channels—especially when driving GaN or N-channel MOSFETs at up to 5A peak—the 2EDN7533RXTMA1 is the better fit.

Design trade-offs
The most significant difference between these drivers is peak drive current and channel count. The 2EDN7533RXTMA1’s 5A peak current (source and sink) enables driving large MOSFET or GaN FET gates rapidly, reducing switching losses and improving efficiency at high frequencies. The MCP1416T-E/OT’s 1.5A peak current is sufficient for moderate gate charge MOSFETs or IGBTs but limits switching speed, which can increase losses and thermal dissipation in high-frequency or high-current applications.
The 2EDN7533RXTMA1’s dual independent channels in a single package reduce BOM count and board space when driving multiple devices, whereas the MCP1416T-E/OT requires one IC per gate channel. However, the MCP1416T-E/OT’s smaller SOT-23-5 package is beneficial in space-constrained designs or where a single low-side driver is sufficient.
Input logic polarity is a critical consideration. The MCP1416T-E/OT is non-inverting, directly passing the input logic state to the output. The 2EDN7533RXTMA1 is inverting, which can complicate gate drive timing and firmware logic unless accounted for early in design. This inversion may also affect dead-time control in half-bridge configurations.
Thermal considerations correlate with switching speed and drive strength. The 2EDN7533RXTMA1’s faster rise/fall times (8.6ns/6ns vs. 20ns/20ns) reduce switching losses but can increase EMI and require careful PCB layout to manage high di/dt and dv/dt. The MCP1416T-E/OT’s slower edges are less demanding on layout but may increase power dissipation in the MOSFET and driver.
The supply voltage ranges are close, but the 2EDN7533RXTMA1 supports up to 20V, allowing slightly more headroom for bootstrap or supply transients. The MCP1416T-E/OT tops out at 18V, which is usually sufficient but worth noting for designs pushing voltage limits.
Lastly, cost and availability should be considered. The MCP1416T-E/OT, being a simpler single-channel driver in a smaller package, will generally be lower cost and easier to source in volume for basic applications. The 2EDN7533RXTMA1’s advanced features and dual channels come at a higher price and PCB area cost but deliver greater performance.
Use-case fit
Choose MCP1416T-E/OT when…
- Driving a single low-side IGBT or MOSFET gate with modest gate charge (<50nC) in cost-sensitive, space-constrained designs.
- Operating at moderate switching frequencies (<100kHz) where switching losses and rise/fall times are less critical.
- The system logic is non-inverting or minimal gate drive signal conditioning is desired.
- Thermal dissipation is manageable with slower switching edges and lower peak current.
- A compact SOT-23 package is required for dense layout or handheld devices.
Choose 2EDN7533RXTMA1 when…
- Driving two independent low-side MOSFET or GaN FET gates requiring fast switching and high peak current (up to 5A).
- High-frequency switching (>100kHz) to minimize switching losses and improve efficiency.
- The design includes GaN FETs or N-channel MOSFETs with large gate charge, requiring robust drive strength.
- The system design can accommodate inverting input logic or can implement firmware/logic inversion easily.
- Higher voltage margin (up to 20V supply) or bootstrap voltage is necessary in half-bridge or synchronous rectifier applications.
Drop-in compatibility
These parts are not pin-compatible or footprint-compatible. The MCP1416T-E/OT is in a 5-pin SOT-23 package, while the 2EDN7533RXTMA1 is in an 8-pin PG-TSSOP package with dual drivers. Additionally, their input logic polarities differ (non-inverting vs. inverting), so substituting one for the other requires redesigning the PCB footprint and adjusting gate drive logic or firmware accordingly. There is no direct drop-in replacement scenario without significant hardware and firmware changes.
Alternatives to consider

- IR2110 (Infineon) — High-voltage high/low side driver IC with bootstrap capability, ideal for half-bridge configurations.
- MIC4452 (Microchip Technology) — Single 9A peak driver in 8-pin SOIC, offering higher current drive in a compact footprint.
Each alternative offers different current capabilities, channel counts, and package sizes, so evaluate based on gate charge, switching speed, and board constraints.
