Key Features
- Dual independent high-side MOSFET driver channels enabling half-bridge and full-bridge power stage designs in a single 8-pin SOIC
- Schmitt trigger input thresholds providing robust noise immunity in high-dv/dt switching environments
- Bootstrap-compatible architecture supporting high-side gate drive above the supply rail for N-channel MOSFET topologies
- Lead-free SOIC-8 package simplifying RoHS-compliant assembly in compact motor drive and DC-DC converter PCBs
Applications
The MCP14E3-E/SN is used in half-bridge and full-bridge motor drive circuits where two independent gate drive signals are required for high-side and low-side N-channel MOSFETs. Its Schmitt trigger inputs reject switching noise from high-frequency PWM transitions, making it suitable for DC-DC converters and class-D audio amplifier output stages. Industrial inverters and battery chargers also leverage its dual-channel architecture to reduce gate driver IC count and board complexity.

Frequently Asked Questions
Why does the MCP14E3-E/SN use Schmitt trigger inputs and how does that improve gate drive reliability?
Schmitt trigger inputs provide hysteresis typically of 0.5 V or more, preventing multiple switching edges from noise or ringing on the PWM control lines during high dv/dt transitions. In high-frequency switching converters operating at 100 kHz or above, this hysteresis eliminates false triggering that would otherwise cause shoot-through and MOSFET damage.
Can the MCP14E3-E/SN drive both the high-side and low-side MOSFETs in a half-bridge, and what bootstrap method supports this?
Yes, the MCP14E3-E/SN is designed for bootstrap-based high-side gate drive, where a bootstrap capacitor charged to the supply voltage is connected to the high-side driver supply pin. This allows the driver to swing the gate 10 V to 15 V above the switching node, fully enhancing an N-channel MOSFET even when its source floats at bus voltage.
What package does the MCP14E3-E/SN use and how does it compare to larger gate driver packages in board space?
The device uses an 8-pin SOIC package with a body footprint of approximately 5 mm by 4 mm, making it one of the more compact dual-channel gate driver options. Compared to DIP-8 or larger 14-pin packages, the SOIC-8 footprint reduces board area by up to 60% in high-density power stage layouts.
For a 48 V brushless motor controller, how does the MCP14E3-E/SN handle gate charge delivery for low on-resistance MOSFETs?
The MCP14E3-E/SN delivers peak source and sink currents sufficient to charge and discharge gate capacitances of 10 nF to 20 nF within tens of nanoseconds, keeping switching losses manageable at 20 kHz to 100 kHz PWM frequencies. Its dual-channel output also allows a single IC to drive both legs of one inverter phase, minimizing PCB parasitics between driver and MOSFET gate.
