Key Features
- 4.5 A peak source and sink gate drive current for fast MOSFET switching with minimal switching losses
- Schmitt-trigger input thresholds provide noise immunity for reliable operation in high-dV/dt power converter environments
- Dual independent channels in SOIC-8 with 4.5 V to 18 V supply range covering most DC-DC and motor-driver topologies
Applications
The MCP1404-E/SN is used in synchronous buck and boost DC-DC converters, full-bridge and H-bridge motor controllers, and gate-drive stages for high-side and low-side MOSFETs in power inverters. Its high 4.5 A peak drive capability reduces MOSFET switching time at hundreds of kHz, lowering switching losses in applications such as battery chargers, servo drives, and class-D audio amplifiers.

Frequently Asked Questions
How does the MCP1404-E/SN 4.5 A gate drive current benefit MOSFET switching speed in a 300 kHz synchronous buck converter?
With 4.5 A peak gate current, the MCP1404-E/SN can charge a 10 nC gate charge MOSFET in approximately 2 ns, significantly reducing switching transition time at 300 kHz. Shorter switching edges lower cross-conduction overlap losses and reduce body-diode conduction time in synchronous rectification stages, improving efficiency of the buck converter output stage by several percentage points compared to a 1 A gate driver.
Why are Schmitt-trigger inputs on the MCP1404-E/SN important for noisy H-bridge motor control PCBs?
Schmitt-trigger inputs add hysteresis to the logic threshold, typically 0.5 V to 1 V, preventing false triggering from fast dV/dt transients and ground bounce that are common in high-current H-bridge switching stages. In motor-control boards where 10 A to 50 A switching generates substantial common-mode noise on the control signal ground, the Schmitt-trigger input of the MCP1404-E/SN prevents shoot-through events that would otherwise destroy the bridge MOSFETs.
Can the MCP1404-E/SN drive both high-side and low-side MOSFETs simultaneously in a half-bridge topology?
The MCP1404-E/SN provides 2 independent non-inverting gate drive channels, each rated at 4.5 A peak, within one SOIC-8 package. For a half-bridge topology both channels can independently drive their respective MOSFETs with propagation delays matched to within a few nanoseconds, and the 4.5 V to 18 V supply range supports 12 V and 15 V gate-drive rails common in industrial power stages. Dead-time generation must be handled by the PWM controller external to the MCP1404.
