What are the key features of MCP1403-E/SN?

Dual-channel MOSFET gate driver with 2 independent drive outputs, reducing BOM for half-bridge and push-pull topologies
Schmitt-trigger input thresholds provide noise-immune PWM signal reception, improving reliability in high-dV/dt switching environments
High-side driver capability supporting bootstrap gate drive configurations in 8-pin SOIC-8 package

What is MCP1403-E/SN used for?

The MCP1403-E/SN is designed for DC-DC converter, motor driver, and power inverter circuits where fast, noise-immune MOSFET switching is required. Its dual-channel architecture and Schmitt-trigger inputs make it a practical choice for half-bridge, full-bridge, and synchronous rectification topologies operating from standard logic control signals.

Frequently Asked Questions

What input threshold type does the MCP1403-E/SN use, and why does it matter for noisy PWM environments?

The MCP1403-E/SN uses Schmitt-trigger inputs, which provide hysteresis to reject fast voltage transients on the PWM control lines. This prevents spurious switching when dV/dt noise couples onto the gate drive signal in converters operating at hundreds of kilohertz.

How many gate drive channels does the MCP1403-E/SN integrate, and which topologies does this support?

The MCP1403-E/SN integrates 2 independent gate driver channels in an 8-pin SOIC package, directly supporting half-bridge, push-pull, and synchronous buck converter topologies without requiring additional driver ICs in the design.

In a synchronous buck converter running at 400 kHz, what advantages does the MCP1403-E/SN offer over a single-channel driver?

At 400 kHz switching, the MCP1403-E/SN drives both the high-side and low-side MOSFETs from a single 8-pin SOIC-8 IC, reducing propagation delay mismatch between channels and shrinking PCB area by eliminating a second discrete driver package.
