Frequently Asked Questions
Q1: Can the MCP1416T-E/OTVAO drive P-channel MOSFETs?
A: Yes. While designed for low-side configurations (load connected to high potential), it can drive P-channel MOSFETs by connecting the source to high potential and the drain to the load.

Q2: How can gate drive resistance be optimized to reduce oscillation?
A: A 1Ω to 10Ω series resistor at the MOSFET gate suppresses high-frequency oscillations and matches the driver's output impedance. Compact PCB layout minimizes parasitic inductance.

Q3: Is this device suitable for automotive applications?
A: With an operating range of -40°C to +125°C, it meets automotive environmental requirements. Confirm AEC-Q100 certification for specific variants if needed.
