Microchip TC4427A Dual MOSFET Driver, Low Side, SOIC-8

The Microchip TC4427A is a robust dual-channel buffer/driver integrated circuit designed for reliable and high-speed switching of power MOSFETs. It features a low-side, non-inverting driver configuration, making it an ideal choice for a wide range of power management applications where precise gate control is critical.

Engineered for exceptional resilience, this driver will not latch up under any conditions within its specified power and voltage ratings. It offers superior protection against environmental challenges, including withstanding up to 5V of noise spiking on the ground pin and accepting up to 500mA of reverse current forced into its outputs without damage or logic upset. All terminals are fully protected against electrostatic discharge (ESD) up to 4kV.

Performance and Features

• High-Speed Switching: Capable of driving high capacitive loads, it can switch 1000pF gate capacitances in under 30ns, ensuring fast and efficient power device operation.
• Low Output Impedance: With a typical output impedance of 7Ω, it provides low impedance in both ON and OFF states, guaranteeing the MOSFET's intended state remains unaffected by large transients.
• Matched Timing: Features matched rise, fall, and delay times for consistent performance.
• Low Power Consumption: Consumes only 1mA with a logic '1' input and 100µA with a logic '0' input, contributing to energy-efficient system design.
• Wide Operating Range: Functions with a supply voltage from 4.5V to 18V and is operational within a temperature range of 0°C to 70°C.

Supplied in a compact SOIC-8 surface-mount package, this AEC-Q100 qualified component is a dependable solution for demanding automotive and industrial electronics, providing the drive strength and protection needed for stable and long-lasting circuit performance.
