TC4421 - 9A High-Speed MOSFET Drivers

Download the TC4421 datasheet PDF. This datasheet also covers the TC4422 variant, as both devices belong to the same 9a high-speed mosfet drivers family and are provided as variant models within a single manufacturer datasheet.

General Description

TC4421/TC4422 are high-current buffers/drivers capable of driving large MOSFETs and IGBTs.

These devices are essentially immune to any form of upset, except direct overvoltage or over-dissipation.

They cannot be latched under any conditions within their power and voltage ratings.

Key Features

  • High Peak Output Current: 9A.
  • Wide Input Supply Voltage Operating Range: - 4.5V to 18V.
  • High Continuous Output Current: 2A Maximum.
  • Fast Rise and Fall Times: - 30 ns with 4,700 pF Load - 180 ns with 47,000 pF Load.
  • Short Propagation Delays: 30 ns (Typical).
  • Low Supply Current: - With Logic ‘1’ Input.
  • 200 µA (Typical) - With Logic ‘0’ Input.
  • 55 µA (Typical).
  • Low Output Impedance: 1.4 (Typical).
  • Latch-Up P.
