What are the key features of MCP1403-E/P?
- Dual-channel high-side capable MOSFET driver with Schmitt-trigger inputs for noise-immune operation in electrically harsh environments
- Up to 4 A peak source/sink current per channel enables fast switching of large-gate-charge power MOSFETs to minimize switching losses
- 8-pin DIP through-hole package simplifies breadboard prototyping and retrofit designs without requiring SMT assembly equipment
What is MCP1403-E/P used for?
The MCP1403-E/P is designed for driving power MOSFETs and IGBTs in switch-mode power supplies, motor drives, and synchronous rectifier stages where fast, high-current gate transitions are critical. Its Schmitt-trigger input threshold provides robust operation in noisy inverter and half-bridge environments. The dual-channel configuration allows a single device to control both the high-side and low-side FETs in a push-pull or bridge topology.

Frequently Asked Questions
What peak gate drive current can the MCP1403-E/P supply to a power MOSFET?
Each channel of the MCP1403-E/P can source and sink up to 4 A of peak gate drive current. This high current capability allows it to charge and discharge the gate capacitance of large power MOSFETs very quickly, reducing switching losses and enabling higher switching frequencies in buck, boost, and half-bridge power converter topologies.
Why do Schmitt-trigger inputs matter in a noisy power-conversion environment?
Schmitt-trigger inputs add hysteresis to the input threshold, typically around 0.5 V to 1 V, preventing false triggering from ground bounce, inductive kickback, and high-frequency noise common on motor drive and switching regulator PCBs. This results in cleaner gate pulses and more predictable MOSFET switching behavior compared to standard CMOS threshold inputs.
How does the MCP1403-E/P compare to single-channel drivers when designing a half-bridge circuit?
Because the MCP1403-E/P integrates 2 independent driver channels in one 8-pin DIP package, a single device can drive both the high-side and low-side MOSFETs of a half-bridge or synchronous buck stage. This halves the package count versus using two single-channel drivers, saving board space and BOM cost while delivering up to 4 A peak current per channel.
Which motor-control scenarios benefit most from the DIP-8 package of the MCP1403-E/P?
The through-hole 8-pin DIP package is particularly useful for prototyping DC motor speed controllers, stepper motor drivers, and solenoid drive circuits on stripboard or socketed evaluation fixtures, where SMT reflow is not available. It also suits industrial replacement boards that specify through-hole components for enhanced mechanical robustness under vibration up to the component's rated temperature range.
