MCP14700T-E/SN

Overview

The MCP14700T-E/SN is a half-bridge MOSFET gate driver manufactured by Microchip Technology in an 8-SOIC package. It features two independent drivers with non-inverting inputs, designed for N-channel MOSFETs. The device operates within a supply voltage range of 4.5 V to 5.5 V. It provides peak output currents of 2 A source and 3.5 A sink capabilities. Key electrical parameters include a propagation delay of 36 ns, with rise and fall times of 10 ns each. The component supports an external dead-time control feature and functions reliably across a junction temperature range of -40°C to 125°C.

Feature Summary

• Supports external dead-time control for precise switching management
• Provides high peak current drive capability for efficient N-channel MOSFET switching
• Features fast propagation delay and transition times for high-speed applications

Applications

• Half-bridge power conversion circuits
• DC-DC converter topologies requiring isolated or non-isolated gate driving
• Motor control systems utilizing N-channel MOSFET bridges

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the '-E' grade corresponds to the industrial temperature range requirements of your application. Ensure the 8-SOIC footprint matches your PCB design constraints. Cross-reference the datasheet revision date to ensure compatibility with latest electrical specifications before finalizing procurement.

Selection Notes

Select this component when a dedicated half-bridge driver with external dead-time control is required. It is suitable for low-voltage applications operating between 4.5 V and 5.5 V. Consider the 2A/3.5A output current ratings against the total gate charge of the target MOSFETs. The non-inverting configuration simplifies logic interface design compared to complementary input drivers.

Part Context

This part belongs to the MCP14xx series of MOSFET gate drivers from Microchip Technology. It is specifically engineered as a half-bridge solution, distinguishing it from single-ended or full-bridge variants in the same family. The SOIC-8 package offers a compact form factor suitable for space-constrained power electronics designs.

Replacement Considerations

Check for direct pin-compatible alternatives within the MCP1470x family. Verify that substitute parts maintain the 4.5V–5.5V supply voltage range and similar propagation delays. Ensure any replacement also supports external dead-time adjustment if that feature is critical to the circuit design.
