Microchip MCP1401T-E/OT Inverting Low-Side MOSFET Driver, 500mA, SOT-23-5

The Microchip MCP1401T-E/OT is a high-speed, inverting MOSFET driver engineered for precision and reliability in switching applications. It delivers a peak output current of 500mA, providing robust drive capability for MOSFET gates. The inverting single-channel output is directly compatible with TTL or CMOS logic levels, operating from a 3V to 18V input range, offering excellent flexibility for various digital control systems.

This device operates from a single power supply spanning 4.5V to 18V. A standout feature is its exceptional switching speed, capable of charging and discharging a 470pF gate capacitance in under 19ns (typical). This high-speed performance, combined with matched rise and fall times and a short 35ns typical propagation delay, makes it perfectly suited for high-frequency switching applications where timing precision is critical.

Key Performance Features

• Low Shoot-Through Current: The output stage is designed to minimise cross-conduction current, enhancing efficiency and reducing heat generation.
• High Noise Immunity: The driver is highly resistant to latch-up and can withstand noise spiking of up to 5V (of either polarity) on the ground pin without damage.
• Low Output Impedance: Provides low impedance in both the on and off states, ensuring the MOSFET's intended state remains stable even during large transient events.
• Robust Construction: The device is AEC-Q100 qualified, denoting its suitability for demanding automotive applications.

Applications

This MOSFET driver is ideal for a wide array of power management and control systems, including motor drive controllers, switch-mode power supplies (SMPS), DC-DC converters, and other automotive or industrial electronics requiring efficient and reliable high-side or low-side switching.
